Ugh, do you really have to be this nitpicky? Fine, you wrote:

No, it's not generally good enough for a game – only for some games, and not good enough for any game with 3D graphics.

Technically, 32-bit fixed-point numbers have 8-bit more precision compared to 32-bit floating-point numbers, but the real problem is it's quite cumbersome to fully utilize the precision offered by fixed-point numbers as you'd have to keep in mind their numerical range all the time.

Speaking of nitpicky, I thought the gamecube's GPU was integer-driven? And it has plenty of 3D games.
