Children Of Mana comes highly recommended from the rpg realm. Also can't stress enough how good WarioWare: Touched! is for some light fun

For an RPG or RPG like game I would suggest Mario & Luigi: Bowser's Inside Story

Others would be:
Ocarina of time 3D (awesome remake)
Kid Icarus Uprising (awesome kid icarus reboot)
Pokemon Alpha Sapphire/Omega Ruby (It's Pokemon )

I actually have and played all of those except Kid Icarus. M&L: BIS is possibly my favorite DS game to date.
