Buying a new game - need tips

I'm planning on trading in my Tomb Raider game on Tuesday for another lengthly, more interesting game. But I don't have any clue which game to choose between. It has to be returned on Tuesday maximum for the "10-day return and get your money back" policy. Any suggestions would be appreciable. Below is a list of the games I already have. 

Dead or Alive 4, Oblivion, Dead Rising, Tomb Raider, Call of Duty 3, Gears of War, Marvel: Ultimate Alliance, Splinter Cell: Double Agent, Rainbow Six: Vegas, Fight Night, Project Gotham Racing and Test Drive.

I also owned/played these games: GRAW, Condemned and Enchanted Arms. 

Yea Call of Duty 2 is way better than 3, I've played it on my pc. If you're planning on getting a 360 then you should wait till the newer version comes out, It will have bigger HDD and support for HDMI

Is this return policy at Gamestation?

If you want something lenghty, go for Oblivion if you like RPG's. Its the longest Ive ever played on a game with over 120 hours on my game time.Jenkins_2005

Another game that you may want to consider, although it is not a lengthy game, is Lost Planet. It is just a down right cool as hell, old school quality game that has beautiful next-gen graphics.....especially the explosions. It can be a bit challenging at certain points as well. It is one of the better action/shooter games on the 360 right now as far as I am concerned.
