3D Dot Game Heroes isn't talked about much... It's basically a 3D modeled retro throwback Zelda / Dragon Warrior game... It's a good game, but I can't play it for too long because the art design choices make my eyes hurt. Maybe it's just me, but the blocky 3D models on top of modern era textures clashes too much.
Retro Game Challenge for the DS: MASSIVELY fantastic game. There's a sequel, but since this one didn't get much attention, it was never brought over to the US.
It's basically a compilation of "Famicom" games... near-parodies of NES games... and you have to complete certain challenges within the games to unlock the next game and set of challenges. Once you've completed all the challenges, you can play the games as much as you want... and they're all really fun, arcadey, NES-type games.
