Disgaea is a must, but find it NOW! It is going to become very rare. I also got Jeaane d'Arc, and I was impressed. For the moment I got to play it. There are also the Tales of PSP remake imports (what a mouthful). Only Eternia is in Engish though, and even then still an import (not released in America, but England). Phatasia and the real Destiny II are also out (but import from Japan only). Valkyrie Proifle I heard was also good. Thes are all of the RPGs I can think of, since you mentioned them.
