And there’s game developers who develop game engines thinking they are developing games.
- with the advent of all the AI tools, is it actually possible to vibe code a 3D FPS shooter from scratch like if you wrote a 2000 page prompt, can it actually be done?
You could try planning ahead and restricting assets to an asset library, that could fix some of that problem. But having used coding agents for complex software work, and games being one of the most complex software tasks in the industry, I just don't see it happening quite that easily.
I also think the outcome would be shit, pure and simple. The development of a game is usually the stylistic input of dozens to thousands of humans over the course of years. They are not trivial pursuits. There's a lot of variance in there, but generally speaking I expect this to be one of the final frontiers for AI development. There's not heaps of training data since game code is usually proprietary, which doesn't help.
I'm sure an LLM could output something or other that resembles a vague concept of a game but you're not going to prompt your way into something that's actually fun for a human to play.
But I have half vibed an FPS in Pygame so its 100% viable (Mine is First and Person, and has motion, but its more of a flight simulator. I am sure the rest of the features would be piss easy)
With that said, yeah Claude Code CAN build one, but for action games a big part of them comes down to “game feel”, something that can’t be captured in a screenshot. You really need to have taste and the ability to describe what isn’t working and why.
