cdoublejj: Yeah, I stumbled on this page from Google. Apple ditched an important bit of software called Rosetta. Rosetta runs older Power PC apps and games and does an okay job with out really causing problems or system slow downs it also doesn't take up a whole lot of space either but, regardless they dropped it after Snow Leopard.
With out Rosetta you can't play early Mac native games such as Fallout 1, Fallout 2, Warcraft 3, Diablo 2, Starcraft 1 and more. So if you have an OS X system newer than than Snow Leopard You cant play the above games or any other Power PC game (*as of this writing) with out some form of emulation or Wine, whihc don't work the same and are usually dos ports or when using wine are buggy and don't always run well or at all.
Rosetta is out of support for apple, but there are other valid emulations. Personally I would recommend simply installing snow leopard into a vm.
/ and similar open source solutions could work as well.
