Halo 3 is hard to beat in terms of quality and quanity imo. Not many games out there allow you to desgin your OWN GAMETYPE, redesgin maps, and play in various game modes. Grifball, MLG playlist, BigTeamBattle, Head to head, Multi-team, and endless variety of custom games. Infection/Zombies is the most popular custom game. Also, there aren't many games where you can record moments of DEAF PRIDE, like in this picture
Halo 3 Screenshot Viewer A guy calls me a 'Stupid Deaf N****R' before the match even starts. I splattered him twice, and when I had some quality one-on-one time with him, I teabagged him, took a pic, and sent it to him. Needless to say, he was PISSED and sent me 4 texts showing how unhappy he was.
