The really old NES RPGs are too simple for me.

I like the 16-bit turn based RPGs as well as the current gen action ones. I love the Tales and Star Ocean series, both have action battles. And I'm currently going through Mass Effect which is really really fun and the battles are all 3rd person shooting.

Complicated RPGs are fine as long as its not overwhelming and complicated just for the sake of being complicated. Something like Shin Megami Tensei Nocturne is too much for me, but Persona 3 is fine.
