If it is a borrowing system- like you can borrow this game of mine while I borrow that game of yours- we would need to keep up with who has what. Or it could be an actual trade to keep thing.
we could post all of the "available for trade" games in one place and go from there. Kinda like putting them all in a pot. We could also put up requests for games.
Maybe even for those of us who don't have much to trade we could set up a regular game-for-money type of exchange. That would be easier than going to the stores and giving it to them for some shitty price and then your friend going in and buying that game for three times what you got for it. Eliminate the middle man.
This just sounds like a really good idea.
You dont have to take any of my suggestions. I just got a little over excited.
