I have a copy of COD3 available for trade. I haven't played it since Gears of War is essentially the only game I ever play, along with Viva Pinata and my Wii.

Here's what I'm willing to trade for:

other 360 games (throw me offers, PM or in the thread)
gamecube memory card
gamecube games (throw me offers, PM or in the thread)

so just PM me if you're interested in trading
