This is a totally loaded question and depends on what kind of game you are into, so allow me to break it down across categories.

Sports = Fght Night 3

Arcade racer = Need for Speed Hot Pursuit

RPG = Oblivion

Shooter - Scifi - GEARS

Shooter realistic - Rainbow Six Vegas

Sim Racer - Forza 2

 Action Platformer - Crackdown.

Depending on what you like, every game on this list will satisfy that urge - there are obviously a bunch more to get, but if you want just one - each game on this list has great replay value. enjoy!

Tasman obviously has a genius level IQ.  And for that we cannot be upset with him/ her/ IT when reality escapes it's grasp and/or the fact that they make such negative posts that they do so in the comfort of their mommy's basement, safe and secure.

 Knowing here on the Internet is the one place they are safe to speak out of turn with no chance of someone smacking the taste out of it's mouth.

Ladies and Gentlemen I ask you to please ignore the foolish and be comfortable in the fact that someone will be taking their lunch money tomorrow :)
