Best Handheld RPGs for PSP or DS

[Ultima Shadow]

TWEWY is easily the best game by far that's been mentioned.

Super Robot Taisen SAGA: Endless Frontier is -super- fun.

This. These two are my two favourite DS titles, TWEWY taking the first place and Endless Frontier coming in second. After that, I'd probably say the Ace Attorney games.

As for PSP... Dangan Ronpa, the Persona games, Mana Khemia and Ys Seven are all very solid.

Dangan Ronpa is very plot/dialouge-heavy, while Ys Seven is all about the gameplay.
