I think it would be an instant hit, as a bunch of us should have Gamecube or Gameboy games that we would like to trade or sell.

Of course theres a chance of fraud always, but I don't think PGC would be legally binded in any way. We could always use heatware (heatware.com) and ebay references. Lots of us frequent other boards with for sale / for trade forums, but this PGC forum would be much easier as there would be a bunch more games out there.
What do you guys think? Thanks.
