The Big Three for Kingdom Hearts

[Marth]

I don't think it has anything to do with "people talking about it", it's more along the lines of the fact that the game/series wasn't built to play that way. It's always been about exploration and a very fluid active combat system. I don't think turn based battles were ever part of the core vision for the series nor are they going to be. They just sort of gunk up the flow of the game.
