Spider-Man in Skyrim: how AI could change modding forever
Merging games is pretty easy with the help of AI. Videos featuring mashups of the sort are currently racking up millions of views. But while social media users are amazed, experienced developers fear the decline of gaming culture.
Not a day goes by without at least one new AI story. Today, it’s about gaming: over the past few days, videos of game mashups have been going viral on X. A mashup is a combination of two or more games, such as World of Warcraft and Call of Duty: World at War.
AI makes it all possible. Put simply, prompts reconstruct the game code, create the assets needed for the crossover and finally generate demos or even just gameplay videos. This way, Spider-Man can swing through Skyrim, for example. It’s highly doubtful that all of these videos actually feature playable builds. Nevertheless, there’s an active conversation around mashup mods.
The videos have been met with enthusiasm by many users, while others – including actual modders – are criticising the trend toward AI-generated game content. If AI mods do indeed catch on, it could flip the modding scene on its head.
Claude Opus 5.5 codes faster and at a lower cost
Mind you, game mashups weren’t invented by AI. Mods that allow characters from one game to be integrated into another have been around for ages. Only usually, it’s fuelled exclusively by creativity, a lot of passion and above all a tremendous workload. But it results in fan projects that often attract a large following – just like many other mod types. They all allow games to be enhanced with additional functions.
Developer studios often provide interfaces for modifications and support the modding community, as it continually develops new content for their games, thereby keeping them relevant for longer. Modders typically devote a large portion of their free time to these projects, and most mods are available as free downloads in workshops.
These AI-generated mashups, on the other hand, are created through what’s known as vibe coding. People instruct an AI agent to combine multiple games without needing extensive programming knowledge. The painstaking work that takes humans months or years to complete is done by AI in a fraction of the time. It analyses the original code, writes new lines, compiles everything, runs tests and delivers a tech demo. No need for developer interfaces, since AI writes the game code itself and thereby creates its own version of the game.

The current mashup trend is being driven by AI agent Claude Opus, which specialises in software development. The new version, 5.5, was released in late September. Anthropic, the company behind Claude, states in its announcement that Opus 5.5 is significantly more powerful and requires fewer resources than its predecessor. This is also reflected in the pricing model and directly results in the agent being used more widely for purely recreational projects.
Human creativity falls by the wayside
True, AI is a powerful tool that can help bring exciting projects to life. But it becomes problematic if vibe coding actually finds its way into the development of game mods. Workshops could be flooded with cheaply produced and often broken content. AI mods only simulate common gameplay behaviour. You can’t recreate every situation the developers intended, and as a result, AI-generated versions of a game are merely an incomplete imitation of the original.
According to IGN, the latest mashup videos already highlight some issues. NPC enemies ignore the player character, spaceships fly in the wrong directions and assets look cheap. This doesn’t even cover error sources in the code that can cause compatibility and stability issues during gameplay.
But even if the quality were acceptable, developing such mods would require only a fraction of the effort a human would need to put in. The end result: genuine fan projects would get lost in the crowd. In turn, this would raise the question of whether human-made mods are even needed any more. If, in the future, anyone can modify their own game using simple prompts, mod workshops might become obsolete.
For many gamers, the modding community is a creative nexus that allows them to interact with other fans. Creating custom mods could cause this community to wither away. Given this, modders are highly critical of the development.
«If this becomes the permanent state of modding, this may be my last project,» writes one author on X. Another user claims to use AI in the development process itself, but describes the mashup videos as AI slop devoid of any creativity. Musicians are also grappling with this problem as streaming platforms gradually adjust their upload policies.
AI mods raise copyright concerns
Currently, AI-generated mashup mods are rarely seen in popular workshops. Major platforms such as Nexus Mods and the Steam Workshop also only allow content that has permission to use the assets. This rule applies especially to AI-generated content. However, Nexus only removes mods if there is a credible complaint from the rights holder.
And since AI doesn’t seek permission before reconstructing code, most mashup videos could infringe on copyright. So far, there have been no statements from major studios. The mashups don’t use official interfaces; they simply recreate games or parts of them. A trend such as this can’t be in the best interests of rights holders. At the moment, however, it’s largely a social media phenomenon that could fade away again.
If, however, a large number of AI mods were to find their way into workshops, human-made projects would also come under general suspicion. In the end, it’s not just modders – who put a lot of work into their projects – who suffer. Players who enjoy playing high-quality mods and discussing them with others will lose out too.
