This is including DS games!

I've been starting to build up my DS/3DS library lately. Just picked up Radiant Historia and the Dragon Quest games, and I'm trying to decide if I want to play that or Bravely Default at the moment. Anyways, I figured I'd ask you all what games have been your favorites as a means to help me figure out what I want to look for next. The consoles have so many good games, and it could be fun to talk about the highlights as well!
