Final Fantasy X. Even though it makes me cringe at parts I love it!!!
Baldur's Gate: Dark Alliance 1 & 2. Me and my brother played the crap out of those games. (The first one had a better story but the second had better perks).
Playing through Rogue Galaxy and it's easily one of my favorites right now!
Silent Hill 2, I was addicted to that game for a good while.
I don't know if they really class as RPGs but I would say Legacy of Kain: Soul Reaver 2 and Legacy of Kain: Defiance. They were SO fucking good and I still love the first game a ton to this day as well despite playing it on Dreamcast and PC. Would have to go back to them and see how well they've aged.
