I'm gonna throw a few classics out there as a reminder because you didn't list them even though judging from the rest you mentioned I imagine you've gotten to them already....
-Breathe of Fire (particularly 3 and 4)
-Some of the weird "Mana Series" titles (Legend of Mana and Sword of Mana were decent IMO)
-Lunar Silver Star and Eternal Blue
now for a few that aren't classics but are certainly just as delightful
-Dark Cloud 2
-Growlanser (a must)
Next, I'm going to second byter's suggestion...
-Rogue Galaxy (I only sampled it, but I know when I get to it this will be one I really enjoy)
and now for something entirely different I am probably alone on....
-.hack series (the current object of affection, a gem that passed me by that I almost sold and am currently completely enthralled with)
and lastly some newer gen stuff I really enjoyed....
-Disgaea 4 (3 was good, 4 was freakin' awesome as far as SRPG's are concerned, highly entertaining)
-Hyperdimension Neptunia MK2 (no need to play 1, it was BAD, 2 on the other hand was quite addicting for me.... silly narrative, not epic in any sense... but somehow, all the ridiculous over-the-top-anime-fan-service aside, I really liked it.... WARNING: DO NOT INGULGE THIS UNLESS YOU LOVE/ARE AT LEAST COMPLETELY COMFORTABLE WITH HEAVY ANIME INFLUENCE AND STUPID 4th WALL BREAKING HUMOR)
-Agarest War 2 (unlike 1 and zero, 2 completely rocks.... 1 and zero are not necessary at all to understand the narrative of 2 BTW)
