Whatever you guys do, buy it, and/or get it working quick.
The game is awesome, I have the mac version (Aspyr) for my iMac.
The only thing is there isn't a lot of mac players on there, mostly PC (yes, it's cross platform with the 1.7 patch). Every time I play people are talking about
what speed their PC is, or video card, or blah, blah, blah. I type in that I'm playing off a mac and people either say: "what?, really?" or that I'm a dork. Granted they're probably 15 years old and I'm old enough to be their mother's boy-toy, but still, we need more mac players out there.
