Elite Beat agents
Animal Crossing
Phoenix Wright
if you like racing games what about Race Driver:Create and Race.
Advance wars
Metroid Prime hunters (as long as you think of it as an FPS instead of a traditional Metroid)
Trauma center
Warioware
I would also get Brain training myself but some gamers might not want to.
Edit... Fkusumot beat me to Elite Beat.
and Picross for the puzzler in you (along with the other two puzzle options given above)
