I think the only one that really had a turn-based battle system was Final Fantasy X... the other ones were active time bar based where you had to wait for the bar to get filled to do something, not wait for your turn.
Well, whatever... I think that nowadays, I'd probably prefer an action JRPG like Final Fantasy XV over a turn based one... if it's done well and isn't repetitive, that is. But that doesn't mean I don't like turn based ones anymore. The last "turn-based" one I really enjoyed was FFXII but I played it "wrong" (didn't use the gambits and did everything manually because I wanted to control everything my characters did :P)
I wish FFXV was a launch game :S
