Thinking of renting a game.....

I have the following games:

Call of Duty 4, Halo 3, Gears of War, Madden 08, Splinter Cell: Double Agent, Ulimate Alliance, Forza Motorsports 2, Guitar Hero III and Rock Band.

What would you consider me to rent?

NHL 08 is phenominal for sure.....NBA 2K8 is also great.....depends what your looking to play

GRAW 2 is pretty tactical andd you seem to like shooters.....Vegas is great, also tactical.........COD 2 has a great story line, COD 3 has fairly good WW2 Multiplayer (depends who you ask) , Oblivion would keep you busy for a looooong time......PGR 4 is a great arcadish sim multiplayer......Assassins Creed is really fun, its a perfect rent same with Bioshock......MAss Effect would also keep you busy for a while

My vote: Rainbow Six Vegas for a tactical shooter that has great multiplayer.....or Assassins Creed / Bioshock because they have a great storyline but doesnt really offer too much in the way of replayability and there for they are perfect rents

I really like shooters/action/sports, and I've already got 4 action/shooter/sports games. I'm kinda looking towards RSV, but idk.

If your getting just overnight or a few nights rental, then Assasins Creed is great...

If your getting a 2 week rental or somewhat then Mass Effect or Bioshock...

Mass Effect has up to 50 hours of gameplay so unless you got plenty of time to play I wouldnt rent it...

judging by your game collection id say you like a blend of fps rpg and strategical thinking i would recomend MASS EFFECT

Rent Assasin's Creed, then don't buy it, its one of those games where you beat it once (and pretty quickly) and don't feel like playing it a game.

If you're renting a game and hoping to buy it in future, then choose Bioshock or Mass Effect.
