I've got a couple of things for sale or trade:
New Super Mario Bros. for DS - perfect condition but just not my type of game. $25 shipped.Bang!
2nd edition and Bang! Dodge City
expansion card games - both are complete and in perfect condition in their original boxes. $10 shipped.
As far as trades I'm looking for some DS games: Tetris DS, Trauma Center, Battles of Prince of Persia or Mario & Luigi DS.
