Out of all the different RPGs, which ones have the best battle systems? Do you prefer classic turn based like Phantasy Star, real time stuff like Star Ocean, or each character getting their own turn as in Shining Force? I'm sure there are lots of other battle systems I can't think of at the moment, so if you like something else better, tell us about it!
Personally, I prefer the original turn based system seen in so many classic games.
