So far i've gone through 3 games since getting the 360 last month on black friday those games being in order.
and Gears of War.
I've also played some of Brothers in Arms: Hells Highway. GRID. and Assassins Creed.
Out of the 3 games played but not finished, i really really enjoyed BiA:HH, was a REALLY fun shooter and kinda hard, great sniper cam too.
GRID i just picked up yesterday, and its pretty cool, sound effects are kinda lame...
