Can you guys reccomend me so good PSP JRPGs?

I have Brave Story, Crisis Core, Disgaea, Jenne Darc, and Valkire Profile.

I want Crimson Gem Saga, but are there any other hidden gems on the system that i should get?

if you have a iphone get zenonia

Star Ocean: First Departure, Star Ocean: Second Evolution.

Star Ocean remakes and Lunar remake( commin out in the Fall)

I was just about to mention Crises Core, but other than those you mentioned the only other non-MMO JRPG's I can think of are Final Fantasy I & II

What about FF tactics: war of the lions? Isn't that one of the best reviewed PSP games? I know it's a remake, but the original is a pretty a amazingly addictive game.

Tales of the World: Radient Mythology.

I beat the first Star Ocean (SNES), and i did not really care for the 2nd(PS1).

Crimson Gem Saga is great.

I'd recommend Class of Heroes, Yggdra Union, the Star Ocean remakes, Phantasy Star Portable, Disgaea, Gurumin, Legend of Heroes series (not great but still fun), and Tales of the World is also fun.

If you like Crimson Gem, then also pick up Ashitonia Story.

Really? I heard that game was pretty bad, with it being mainly mission based with not much of a storyline.
