I mean I crafted complete complex game prototype using Gemini 2.5 Pro with nearly zero coding. I done it in a week: with client-server architecture, robust networking, AI, acceptance test coverage, replays.
It just different way to build software. You just spend 30% of time on specification, 30% on testing and 30% on refactoring also using AI.
Actual slop generarion take like 10% of time and rest of the time you turn it into maintainable code.
Of course you can do it manually, but then it will take 5-10 times the time and you wont be as flexible in changing things because with AI you can do major refactoring in a day, but manually it could take weeks and kill the project.
You're free not to believe me, but I do shipped 3 commercial games (links in profile). I know that what would usually take to build 2-3 months of developer time can now be built in a week.
PS: I might eventually post here about rapid game prototyping with LLM.
If you actually have some credibility feel free to reach me via Linkedin or non-anonymous email and I'd happily share my experience or the code.
