I finished Dragon Quest IV not too long ago. The gameplay, as I said before, was much more entertaining once the game stopped starting over with level-one characters every few hours.
Still, I’d have to rand DQIV as one of the lesser RPGs I’ve played. It’s worth playing through once, but I’ll probably not pick it up again because everything it does has been done better in later RPGs – and there’s no great story or characters to want to experience a second time.
