Are there any good mac games out liek counter strike or delta force 3 or a good mulitplayer game like that??

I just got Skyfighters 1945, its a flight sim (don't know it if thats what your looking for). Its pretty cool, get to fly mustangs, ME-109s, spitfires and and you can play up to 8 people over the web. You need a 3D card, but the game is worth it.
