yea Gamespot stopped accepting any buybacks of nes, snes, genesis,
n64, and DC games back in February. Then just about all the games
were gone. But just recently they either took all the games that got
sold before that buyback initiative and cataloged them and put them
up for sale or they received a shipment of games from their headquarters
(the latter is unlikely, so it's probably the former).
Anyways, they now have tons of nes,snes,genesis, and n64 games again.
I even saw Paper Mario...
