I just picked up a lot of 3DS games for $125. The lot included 10 games and all were hardly used and complete.
Mario Kart 7
Super Mario 3D
Ocarina of Time 3D
Pilotwings Resort
Tetris Axis
Resident Evil The Mercenaries 3D
Monkey Ball 3D
Lego Pirates of the Caribbean
Nintendogs and Cats...
Professor Layton and the Unwound future and Kirby's Epic Yarn. I would highly recommend both of these games.
Oh yeah, I also picked up a copy of Okami for the Wii. It is even better than I had hoped it would be!
