I disagree with all the nay sayers here. This is a game against the pinside pricing system. For example, I have a Cleopatra that I briefly thought about offering. Pinside values it higher than Monte Carlo. I've never owned a Monte Carlo and it looks looks interesting. I bet if this was played right, both parties could win. Unfortunately, I'm not willing to travel for that trade.

OP could also be taking some risk by having the games brought to him. I've had some bad trades brought to me when I trusted the other party. If they're coming from a distance, it's hard to thoroughly go through the game for the first time when it's on your front porch.

I'm interested to see how far this gets.
