Learn MoreWelcome to the second part of our series on game modding. If you missed the first part, where we explored the history of modding and its impact on the gaming industry, we recommend checking it out at Skillbox Media. In this article, we'll take a closer look at the different types of user-generated content created by players and offer helpful tips for aspiring modders on how to upload their creations. Learn more about how mods can enhance your gaming experience and the steps you need to take to create and publish your own mods.
A Scientific Approach to Classifying Game Mods

Game modifications have unique characteristics, allowing them to be classified into several categories. One such classification is the study "Modders of Skyrim: Motivations and Modifications." In this study, Swedish researchers Eleonora Hackman and Ulfric Björkvist identified eight main mod development trends. These trends help understand which aspects of modding are most attractive to creators and players, as well as which features and changes to the game are most in demand. Mod classification plays an important role in the development of the gaming community and contributes to the improvement of the gameplay experience.
According to Hackman and Björkvist's research, key mod development trends cover several significant aspects. These aspects include the adaptation and optimization of existing processes, which allows for their efficiency and improvement of the quality of results. Another important area is the implementation of new technologies that facilitate the automation and simplification of task execution. In addition, attention is paid to personnel training and development, which allows not only to increase the level of employee competencies, but also to increase the overall productivity of the team. Modifications in these areas contribute to the creation of a more flexible and competitive environment, which in turn has a positive impact on the achievement of business goals.
- Changing the appearance of characters;
- Changing equipment;
- Modifying parameters (item availability);
- Rearranging items (placement);
- Improving graphics;
- Changing locations;
- Improving immersion in the game;
- Optimizing the interface (UI modifications).
It should be noted that many modifications are hybrid in nature, combining various elements. The more aspects a mod covers, the more likely it is to develop into a large-scale add-on or even become a standalone game. This diversity allows developers and players to create unique content, significantly enriching the gaming experience. Hybrid mods can attract a wide audience and expand the capabilities of the original game, opening new horizons for exploration and creativity. There are many classifications of computer game modifications. In one of his studies, Walt Scacci, a PhD candidate in computer science from the University of California, identifies four main types of mods. His paper, "Modding as an Open Source Approach to Extending Computer Game Systems," proposes the following classification: user interface modifications, game content reworks, creation of new game mechanics, and hacking of closed-source games. These categories help better understand the diversity of modding approaches and their impact on game development.
The Hackman and Bjorkvist classification is a useful tool for understanding the various aspects of modding. In this article, we will explore this classification in detail, adding subcategories and specific examples for a clearer understanding. We will pay special attention to the last point of the classification, concerning assistance in creating mods. We will adapt it to focus on changes in the interface, which is especially relevant in light of modern modding trends. This will allow us to better understand how the interface influences the mod creation process and interaction with users.
Character Diversity in Mods
Video game mods are an important tool that significantly changes the gaming experience. Particular attention should be paid to character-related modifications. These mods not only improve visual design but also introduce dramatic changes to character animations and behavior. This allows players to more deeply immerse themselves in the game world and enjoy the unique aspects of the game. As a result, the use of modifications is becoming an integral part of the modern gaming process, allowing each player to adapt the game to their preferences and make it more exciting.

Many games offer a variety of characters, but their detail can sometimes be insufficient. The Total Character Makeover modification for The Elder Scrolls 5: Skyrim, which has been downloaded over 1.3 million times, significantly improves the character models, adding high-quality textures and an increased polygon count. The developers of this modification give the characters new features while maintaining the unique style of the original. This makes the game more attractive and immersive, improving visual perception and the overall impression of the gameplay.
According to statistics from the Nexus Mods website, the Total Character Makeover mod has become popular among gamers, having received almost 6.5 million views. This mod significantly improves the visual characteristics of the characters in the game, which attracts many users. The high interest in Total Character Makeover underscores its quality and relevance in the player community.

Players are always looking for ways to make their avatars Unique, which encourages the development of numerous mods. These mods replace the default models with famous characters from other games or real-life figures. For example, in The Sims 4, there are mods that allow you to control celebrities like Marilyn Monroe or Mr. Bean. Such mods not only add variety to the gameplay but also attract attention to the game, expanding its audience. Unique avatars help players stand out in the community and express their individuality.

Mods that add explicit scenes to video games are controversial among players, but their popularity remains high. Mods like Nude Raider have gained notoriety for their provocative and bold content. Despite criticism, mods like the one for The Witcher 3: Wild Hunt continue to attract attention and remain popular, with over 90,000 downloads. This confirms players' interest in such changes to gameplay and their desire to explore new aspects of familiar universes.
The first nude mod, Nude Raider, was developed for a Lara Croft game and became the subject of heated debate among developers. In 1999, they attempted to prevent the patch from being distributed, believing it was negatively affecting the character's reputation. This incident became a significant moment in modding history, highlighting the influence of the community on game projects and sparking discussions about the boundaries of artistic expression in video games.
Game mods can dramatically alter gameplay by replacing original characters with unexpected models. This creates comical and absurd situations that add a new level of entertainment to the game. A prime example is the mod for Resident Evil 2 Remake, in which Mr. X is replaced by Thomas the Tank Engine. This approach not only evokes laughter but also makes the game more memorable. The introduction of non-standard characters through modifications allows players to see their favorite projects from a completely new side, adding elements of fun and surprise to the usual gameplay.
Mods that allow you to replace original characters with alternative ones are very popular among players who want to see the storyline from the point of view of secondary characters. The Model Swapper mod for Cyberpunk 2077, for example, allows players to assume the roles of various characters, enriching and diversifying the familiar story. Such modifications not only reveal new aspects of the plot but also make gameplay more engaging and interesting.
Equipment and its modifications
Equipment modifications in video games are not only a change in appearance, but also a complex process that involves the creation of unique skins for characters' armor, clothing, and weapons. Players can change textures, add new elements, or design entirely new models from scratch. Equipment replacement is one of the most popular forms of modification, along with changing the appearance of heroes. These modifications not only enrich the gaming experience, but also allow players to express their individuality by creating unique looks for their characters.
Changing the appearance of equipment in video games serves many purposes, including creating comic effects and deepening immersion in the gameplay. For example, in Resident Evil: Village, players encounter an interesting solution where a familiar weapon is replaced with a fly swatter. This unusual change not only brings a smile but also adds a unique touch to the gameplay experience, allowing players to enjoy new sensations and increasing their interest in the gameplay. It is important to note that such creative solutions can enrich visual perception and make the game more memorable.

According to Nexus Mods, the Immersive Armors modification for TES 5: Skyrim, developed by hothtrooper44, has been downloaded nearly 3.5 million times. This mod has not only become popular among gamers, but has also received high marks in publications such as TIME, Kotaku, PC Gamer, and Gamespot, which speaks to its quality and demand in the community. Immersive Armors adds a variety of unique armor to the game, which significantly enriches the gaming experience and allows players to customize their characters.
Changing Game Parameters: How Mods Can Improve Your Experience
Modifications that affect game parameters require a deep understanding of its mechanics. These changes can affect the balance of game elements, item stats, the drop rate system, as well as restrictions related to levels, professions, and crafting. While such modifications are sometimes perceived as cheating, when properly configured, they can significantly improve gameplay, providing more varied and interesting interactions in the game. Properly chosen mods can not only enrich the gaming experience but also help players discover new aspects of mechanics and strategy. The Better Generators mod for Fallout 4, created by expired6978, significantly increases the efficiency of generators, allowing them to produce up to 10,000 units of energy instead of the standard 500. This change helps players reduce the number of generators needed, focus on lighting and protecting their settlements, and optimize space utilization for future construction. Improving generators not only increases the comfort of the game, but also contributes to more strategic resource planning in the world of Fallout 4.

Changing the location of objects in In modern games, developers increasingly use modifications, allowing you to change the placement of both new and existing objects within levels. This creates a more realistic and immersive gaming environment. Increased interactivity has become an important aspect that contributes to the player's deep immersion in the gameplay. Modifications not only diversify the gaming experience but also allow players to adapt the world to their preferences, making each game unique.
The "Placeable Statics - Move Anything" modification for the RPG TES 5: Skyrim - Special Edition is a striking example of the possibility of customizing the gameplay. This mod provides players with a unique feature for changing the placement of objects in their homes, allowing them to create individual interiors. Players can easily transform their home into a cozy space or, conversely, organize a mess by adding interactive elements to the design process. This approach not only increases the level of personalization, but also makes the gaming experience more engaging, allowing each user to tailor the space to their preferences.

Modifications such as ‘Move Anything’ significantly improve player interaction with the game environment and open up new possibilities for creativity. According to Game Industry research, over 60% of players are interested in using mods to improve their gaming experience. This fact underscores the importance of customization and the ability to change the game world in modern video games. The development and use of mods are becoming an integral part of gaming culture, allowing players to create unique gaming situations and adapt games to their preferences.
Modern Graphics in Video Games
In recent years, technologies that improve graphics in video games have been developing rapidly. This is due to the redesign of existing 3D models and textures, as well as the creation of new game assets. The advent of remasters and remakes has changed the gaming landscape, but before that, player-generated modifications had become a popular way to update content. Game mods not only enhance visuals but also introduce fresh ideas into gameplay, making them an essential element of the modern gaming experience. Currently, modders are actively using neural networks and machine learning methods to create high-quality graphical elements. These advanced technologies significantly simplify the process of upscaling textures and backgrounds, which not only speeds up development but also improves the quality of the final product. The use of neural networks in modding is becoming standard, achieving impressive visual results and streamlining workflows. The Resident Evil Seamless HD project is a shining example of successful work in the video game industry. A small group of enthusiasts converted the first three installments of the iconic Resident Evil series, making it possible to run these games on PC using the Dolphin emulator. Thanks to this, classic horror titles have received new, highly detailed backgrounds, improved character textures, and updated FMV cutscenes. These transformations not only refresh the games' visuals but also allow new generations of players to relive the atmosphere of the original projects.

Neural networks are actively used to improve the quality of textures in old video games. For example, Gigapixel AI is used in games like Red Faction and Final Fantasy VII, while ESRGAN is used in projects including TES 3: Morrowind and Max Payne. NVIDIA NGX Technology, which was used in DOOM, is also worth mentioning. These technologies significantly increase the resolution and detail of graphics, making older games more appealing to modern players.
Popular Locations in Games
Custom maps, designed with attention to detail and interesting scenarios, always attract the attention of the gaming community. Such content not only maintains player interest but also provides modders with unique opportunities to develop and master new development skills. Some of these modifications have a unique atmosphere, immersing players in completely new game worlds. Creating custom maps not only contributes to a more diverse gaming experience, but also fosters creativity among community members.

Increasing Immersion in Games
Modern game modifications increasingly focus on creating a deeper immersion in the gameplay. Immersion is achieved not only through visual improvements, but also through unique storylines, new characters, and expanded lore. These modifications can develop into full-fledged projects that often surpass the original games, providing players with new levels of interaction and experience. Using such mods not only diversifies the gameplay but also deepens the player's emotional connection with the story and characters, which makes the gaming experience more intense and memorable.
The S.T.A.L.K.E.R. Anomaly modification is one of the most notable projects in the S.T.A.L.K.E.R. fan community. This mod is considered one of the best amateur add-ons thanks to its many useful improvements. S.T.A.L.K.E.R. Anomaly not only fixes bugs and improves graphics, but also offers players various game modes: a story mode with new campaigns, a sandbox mode, and a faction war mode. Furthermore, the mod adds new NPCs, improves the interface and enemy AI, and makes changes to faction design. Starting with version 1.5.1, S.T.A.L.K.E.R. Anomaly has become an independent mod and no longer requires the original files to run, making it accessible to a wider audience of players.


Interface Customization: Improving the Gaming Experience
User interface (UI) modifications are an important aspect that significantly improves the quality of gameplay. Some focus on visual changes, such as stylish frames, icons, and panels, making the game more appealing to users. Other functionality-focused modifications can significantly improve the usability of interaction by changing the HUD and adding useful elements that simplify the perception of information and gameplay control. These improvements not only make the game more aesthetically pleasing but also enhance its functionality, which ultimately leads to a more engaging and comfortable gaming experience.
In MMO games, interface customization plays a vital role in improving interaction with the game world, which positively impacts gameplay without creating inequality among players. A prime example is World of Warcraft add-ons, which boast nearly 9,000 different mods. These add-ons help improve quest navigation, offer advanced maps, and provide helpful dungeon strategy tips. As a result, players can adapt the interface to their needs, which significantly increases the comfort of the game and the efficiency of completing in-game tasks.

It's important to consider that mods can have a negative impact on gameplay. Specifically, in certain games, the use of add-ons can provide players with a significant advantage in PvP battles. This raises concerns about the fairness and balance of the game experience, which can reduce interest in the game for those who prefer to compete on a level playing field.
Several years ago, the World of Tanks community encountered serious issues related to mods. The game did not prohibit the installation of various add-ons, which contributed to the emergence of modifications with questionable legality, such as armor analysis and target display. In response to numerous complaints, Wargaming developers officially banned the use of such modifications in 2017. However, the game's official website still features a section featuring approved mods, allowing players to enhance their gameplay without breaking the rules.
