Hey there, I have all of the 360 titles you have listed, (although I received Gears 2 from Goozex in so-so condition. I could probably make use of your PSN card. Let me know what you had in mind.
The only one I have is a Yahoo one, but that one is for work purposes and can't be given out. If you want, you can just email me the questions you have about it. No big rush.
