Call of Duty:Modern Warfare 2
nobody is asking you to choose between being competitive and just having fun
but dude, playing different games is ok....halo isn't the only thing out there
and i think that widge's point was that having fun is(or should be) the main goal of gaming, anything else is secondary
i play at least 4 different multiplayer games regularly...just depends on how involved i feel like being in a game
