Sorry for bumping a rather old thread. I have played some good action RPGs before like Freedom Force (always confuse this game with another game, Freedom Fighters, a 3rd-person action shooter) and Dark Messiah of Might and Magic (don't know if this game is an action RPG but it does play like one, to me).
As for the worst action RPG, it's Prince of Qin. The worst I've ever played in my life.
