Lol. That task will burn all of the month's allowance in a week, AND cost another $500–1,000 minimum just to get a working player character and some crude, rudimentary buildings.

I just saw that with Claude Opus 4.6, with two weeks of continuous sustained work, they built a C compiler. Game engines are not dissimilar in complexity to C compilers—they model so many things that combined would equal what it takes to build such a compiler.

And that would give you, at best, an ugly but playable game. I think actually the bill for that amount of work comes out to around $20,000.
