Before I had the mac spotlight shine down on me through my dirty windows, I played a few games on my pc. Luckily, its dead now, and im never going back to windows, and have absolutely no thoughts of putting vista/xp on my baby. But schoolwork has been slow lately, and ive seen ever faildogs.com picture, so im wanting to start my CS:S gaming back up, and have a few questions. 1. With 'crossover,' does that allow me to run steam (css) through my mac without installing vista? 2. If so, how cleanly will it run? I have a 20" 2.0 1gb baseline alum. imac. 3. If the aforementioned are successful, who wants to play some welcome-back-to-CS:S games?
