Ok I've got one question.. Should I buy Orange Box for the PS3 or just buy Crossover Mac and buy it in steam? Both have their problems and one is more expensive... so what should I do? (BTW my comp is a 2.4ghz Al iMac w/ 2GB ram). I'd would just go out and buy the PS3 version because it's cheaper but I have heard of problems with that version so I wanted to know what people think of Crossover. Thanks!
