1:Gears of War 2

My list will probably change order but thats the best i can do even with lengthy thought.

Holy **** i forgot Batman Arkham Asylum. That goes at number 2 and bumping out Dead Rising.

10. Red Dead Redemption

9. Grand Theft Auto IV

8. Batman: Arkham Asylum

7. Banjo-Kazooie: Nuts and Bolts

6. Mass Effect

5. Mass Effect 2

4. Halo: Reach

3. Rock Band

2. Gears of War

1. Halo 3

No order for the list, just numbered it so I would know when to stop. :P

1. Vanquish- Most intense shooter available (My 2010 GotY)

2. Halo 3- Great campaign, great multiplayer, etc (My 2007 GotY)

3. Halo: Reach- Most complete console game ever created

4. BlazBlue: Calamity Trigger- My favorite fighting game ever created (My 2009 GotY)

5. Final Fantasy XIII- Underappreciated game that moves JRPG genre forward

6. Mass Effect- Way better than that dull Mass Effect 2.

7. Tales of Vesperia- Exciting, if traditional, JRPG with fantastic characters and story (My 2008 GotY on 360, overall was No More Heroes)

8. Bayonetta- Best action game released since the original Ninja Gaiden

9. The Orange Box- Good quality package of five different games

10. The Elder Scrolls IV: Oblivion- Probably the most important RPG released this gen (My 2006 GotY)

I think that's how my list would go. I dunno, might change it up a bit if I remember something else, but each of these gaems provided me with dozens upon dozens of hours of fantastic gameplay!

EDIT- Since I mentioned the five GotY games I feel like mentioning that my 2005 GotY on 360 was Project Gotham Racing 3 (though overall would be Resident Evil 4).
