As a PC Gamer, I've discovered I do not have the aptitude for XBOX 360 FPS.
My XBOX 360 came with Gears of War 2, Gears of War and Halo 3.
They are all for trade for sports XBOX 360 games (that are in working order of course) or for sale.
Gears of war 2 I played for approx five minutes. So it is pretty much as new and includes the bonus gears of war 1 map pack detial sinside for free download I do believe. $55 inc postage
Gears of War Unopened. $35 inc postage
Halo 3 (10 mins game play) $45 inc postage.
I would prefer to get an NFL game for one of these in trade, preferrably from 09.
