Any PSP game recommendations?

[dante]

I have a PSP, but there aren't too many games that really have me picking it up anymore. Anyone here have some game recommendations? I'd prefer some lesser-known titles, but any recommendations work.  The games I've played and loved are:

-Final Fantasy VII: Crisis Core
-Me and My Katamari
-Loco Roco
-Metal Gear Ac!d

I didn't enjoy Patapon nearly as much as I thought I would, sadly.

Also, I just played the demo for the upcoming Prinny game. It is pure amazing.

Ideally, this game should move PSP units by itself. Don't know if that will be happening.

I'm going to write a preview right now. And yes, I am going to include a picture of me wearing my Prinny hat.

I don’t have a PSP so my knowledge is limited.

Patapon looks cool.

The only games I ever played on my psp more than once, were Tekken Dark Ressurection, and Lumines.  Oh and the Splinter Cell Essentials game, but that was just fair.
