Are there any real differences in buying a Mac or a PC version of a game? I've been itching to play The Sims 2, along with a few other games, and I'm not sure which one to get. I have Windows installed, via BootCamp, and a few older games I can play on there. I also have a MacBook, so the video might be an issue. From what I understand, the video card can be more productive under Windows running natively than using OS X. Also, is it possible to play on a network against PC users? For instance, let's say we're playing Age of Empires II, and I want to go against a PC user. Will that work, or do we need to both have the same version of the software (both Mac or both PC)?
