You have all of them. I guess I could recommend some mana titles, tales of titles, and I'm enjoying Wild Arms 1 right now, didn't start 2 yet. I see you have 3. Wrpg wise Get baldur's gate 1 and 2(pc games but fairly old, and any pc in the last 10 years should run them. Since you like oblivion I would say get morrowind. I also heard planescape games are excellent. Mario and Luigi Partners in time, Rune Factory FFCC: RoF, Etrian Oddysey( I hated it, but some like it), and FFXII:Revanant Wings are some good rpgs for the ds. Also where is your snes collection, I don't know what snes games you have or not. Psp wise Crisis Core was ok, I've heard good things about Brave Story, and the FF1 and FF2 remakes were pretty good. Thats about all I could recommend you until you tell me your snes rpgs.
Edit: Crap alot of my recommendations are obsolete.
