This game is a prime reason that I dont toss out my old computers... some apps and games are just too dame good to let go of! I dusted off a 10 year old Mac runing 10.6 just so that I could play this classic game. The game play (and even graphics) hold up well even today. I still play COD2 (on a modern OS, go figure) and I actually feel that the orginal COD is not only more fun to play, but has equal grafics.
