I just learned firsthand that games on the Mac do suck.. the rumors were true.
yes saladfingers, 2142 mac DOES suck... but not games in general.
2142 isn't a normal port... it's a CIDER port. Cider is a cheap way to do porting because you don't have to recode much of the program... Cider simply converts the code on the fly. This means you take a performance hit. I don't know if all cider games are inherently bad, but either way, 2142 is a POOR job of porting.
Quake 4, on the other hand, is a well ported application. It runs faster than 2142 does for me, and it also looks better at the same time.
And this is actually a windows user talking about how 2142 runs crappy on Windows for him (

2142 is fun, but the quality of the engine leaves much to be desired : \
