Favorite of all time has to be FFXIII love how it redefined final fantasy. But right playing kingdoms of amalur reckoning and holy shit is it fun as hell.
Persona 3 (P4 was good but I like part 3 better) Xenosaga (All three games counting as a whole) Final Fantasy 13 (Started playing this only last month. But its awesome. Out of all the final fantasy games I have played this one is my favorite.)
Parasite Eve would probably be somewhere in my top list. I like the Monster Hunter series quite a bit as well, that's kinda RPG. My favorite traditional RPG would probably one of the Suikoden games.
Infinite Undiscovery, Xbox 360. The characters amuse, the story passes the time along and beating up the little jerk that annoys you is made more fun by making the weapon that takes 'em down.
