I don't think that GoW would be a great purchase if you are looking for straight up multiplayer (on either PC or 360). GoW was great because it was a first gen game with a decent story line that showed some of the power of the newer systems. I really did like the single player portion of the game, and I can't wait for GoW2; however, I only played the multiplayer for a little while and didn't like it all that much. Both Halo3 and CoD4 offer better multiplayer IMHO... GoW is worth it if you can get it cheep for the single player (since it's been out for a while), not so much for the multiplayer.
