What games should I buy out of the following;

Brink
Fallout New Vegas
Gears of War 3
COD Black Ops
Medal of Honour
Mafia 2
Assassin’s Creed: Brotherhood
FIFA 11
Deadrising 2
Halo Reach

I don’t have XBOX Live, but like FPS games because they can be fun without muliplayer and Black ops looks like it might have a decent story. I’m not really into zombie games, but deadrising 2 looks like it might be ok. I loved FO3, GOW 1 and 2, Halo 3 was ok but reach looks sexy, FIFA 11 looks ok, I don’t know what Mafia 2 will be like, loved assasin’s creed, Brink looks fun and medal of honour looks…ok. However, I don’t really know much about any of these games except for FIFA 11, and I want to try and reduce this list down to a smaller size (money is a big factor). Any opinions and news or reviews about these games (links to the website if you can) would be appreciated, and best answerer gets 10 pts.
I already have gta 4 episodes from liberty city, Gears of war 2, MW2 and Bad Company2
