The problem is that he doesn't know structured programming so his game already maxes out a PCs capabilities. He mentions the performance issue in earlier videos. I'd be surprised if his game is under 300,000 lines of code.

Really? According to his website he wrote it in C, which is a structured language. Also on the website he says the framerate on a crappy old pentium 4 is 200 to 300 fps

This game can't hold many more booths without there being Serious Reprocussions

It has it's own economy.

He's put more planning into this level than most actual carnival managers do.
