If you like sports, then you should get NBA 2k9 or NBA Live 09. (Be prepared for a lot of trash talking). But if you like shooting games you should get Killzone 2. Its probably a little early to get because it just came out, but it should give you some time to do the story. Online matches can connect 2 to 32 players, and they can group into squads of up to four players. Furthermore, two squads can group together as a faction of eight players. If an online match does not have a full 32 players, computer-generated "bots" can be added in to create bigger teams. Killzone 2 also has a clan system, which allows clans of up to 64 players to compete for "Valor Points", an in-game currency that clans can use to bet on tournaments.
