Hello everyone. I'm thinking about getting a new game for my mac. I haven't played any games for a long time. Any suggestions for a good first person shooter? Ones I've been considering are Medal of Honour Allied Forces, Rogue Spear, Unreal Tournament and Alien vs. Predator. I've got a dual processor 500mhz with 896mb of ram. What's everybody out there playing? Anything that should be avoided?
