I found this DS game at a local import/hobby store for $5, and I get this quasi-nostalgic feeling when I play it. It's obviously *very* heavily styled after the old D&D adventure games, and my copy even came with a soundtrack CD with some music I would find very awesome to listen to while playing D&D.
Oh... and it's pretty hard... like staying alive as a 1st ed Wizard that rolled a 1 on his first hit die hard. Somehow that makes it really cool, though. It's the first challenging game I've come across in a very long time.
