Halo 2 is going to be a really cool game, personally i am stoked, just one day and it will be out. I also like hl1 and 2 but halo 2 should be just as good, the multiplayer is supposed to have up to 4 players on 1 xbox, and there will be organized clans with there own website on the xbox site! All around it sounds pretty cool and i am excited to see the story line, cuz i liked halo 1 story line. Halflife 2 also kicks ass though.
