AI is Quietly Rewriting Video Games — And No One Knows Where It Stops

Social media feeds have been flooded in recent weeks with strange video game mashups. Skyrim inside Minecraft. Halo, but the main character is Mario. Skate 2 on Call of Duty maps. These clips look professional, and they spread fast. The cause is artificial intelligence. Specifically, a tool called Claude, made by the company Anthropic, has become very good at "decompiling" video game code. Decompiling means reversing a finished game back into the human-readable source code that programmers originally wrote. With that code in hand, anyone can edit and rebuild the game. This process used to take enormous effort. Now, AI does most of the work. The result is a wave of fan-made modifications — "mods" — that mix parts of different games together. The trend raises hard questions for the industry. Modified games can copy protected content, which touches on piracy and copyright law. It also shows how quickly AI is changing what fans can build — and how far it could disrupt how games are made and sold.
