Mario Kart Wii, Roller Coaster Tycoon, and The Legend of Zelda: Majora's Mask

Age of Empires III - We friends still play it because of fun local multiplayer. We all are of same skills so it is very fun when we gather with our laptops in a friends house who has all the lan settings. 

Counter Strike Source -  We also play this game on lan. 

Unreal Tournament 4 - Another game we play.

Halo, Halo 3, Battlefield 1943, and COD 4.

DMC3, P3 and pretty much all MGS games.

It used to be Halo 3, but now it's Gears of War 2.

Fallout 3 - 2008

Oblivion (just re-bought it) - 2005/06 can't remember

CoD4 - 2007

No One Lives Forever - 2000

Pretty much all games that I have played recently where released a while ago the newest game I played recently was Assassin's Creed Brotherhood.  Just beat Uncharted 1&2 last week really good games and fun to play especailly the 2nd one.  Assassins Creed and Uncharted are my favorite new IP's of this generation.

Probably gonna try to beat Brutal Legend later this week.

i beat infamous about once a week....

I could have played and beaten it last week when my younger brother borrowed his college roommates PS3 for sprink break but beat Uncharted 1&2 instead and played God of War I almost halfway through.
