What's the Best Game for a Multiplayer Shooter Noob?

Commenter DeapGalaxy isn't an online multiplayer shooter fan, but he'd sure like to be. Help him find the perfect game in today's thrilling episode of Speak Up on Kotaku.

Okay, I need help with getting a game.

I've never really gotten into the whole multiplayer shooter scene, I've never even owned a single Call of Duty game, not because I'm like "lol cods 4 n00bz", I just never got round to it. But now I want to play a multiplayer shooter game, but because I don't exactly have a load of disposable income I'll have to come to Kotaku to help me choose one since I can't try them all out.

I enjoyed the Uncharted 3 beta, and I will be picking up U3 on day one (Mainly for the single player), but then maybe I should go to something more popular like Modern Warfare 3 or Battlefield 3. I'm looking for a good shooter with a good big community, I only own a PS3 so maybe even something like Killzone 3 or Resistance 3?

Also I'm not too keen on something heavily objective or team based like Team Fortress 2, I don't mind playing in a team, just as long as there's room to do my own thing too!

Could someone help me out finding out which game to choose?
