OKay so depending on your definition of RPG... this list varies, so i'll make it longer.
1. Zelda
2. Zelda 2 (more RPG than the first)
3. Battle of Olympus (close to Zelda 2)
4. Shadowgate (dungeon crawler)
5. Racoon City (errr beat them up with RPG elements?)
6. Dragon warrior (got turned off by the fight with menus... that one was a rental too so I didin't give it an other shot).
I think my first real turn based one that I played were the FFs legends (played adventure and well wanted the same thing but i still liked what I got). Then FFIV, breath of Fire.... and all the ones I could get my hands on on the SNES after that.
7. FF Adv
8. FF L 1
9-10-11 FF L2-3 IV
Edit:
OOps forgot some....
insert between 4 and 5 :
Les Chevaliers du Zodiac ( Saint Seiya ) (like zelda 2, many RPG elements... also with actual menu fights if I recall? would make it a real RPG and my first)
Dragon ball (NES) like a mix of zelda and street fighter (bosses were street fighter type fights :p) but with RPG aspects...
OoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoO
