I've occasionally been poking through the Super Famicom remake of the original Dragon Quest on my cell phone -- you know, when I've had downtime and haven't had my PSP or DS or suchlike with me.
First of all: man, onscreen D-pads suck, even for games that require as little precision as DQ. I have to savestate-spam just to get around the outside wall of Rimuldar without accidentally walking out.
Second: there's so much that's wonky about the interface of this remake. The stupid little half-steps you take instead of moving a full tile at a time, the bizarre decision to stick the action button on X and leave the menu on A (something they stuck with on up through 7 on the PS1!)...frankly I'm almost inclined to tip the Game Boy remake as the superior version of the game despite its inferior graphics and sound, just on its smoother interface.
(Also I recall the GB version having a more charming translation. I probably snorted out loud in class when I took the Princess to an inn and the keeper remarked the next morning that we'd sure been up late last night.)
(Yeah, I played Dragon Quest in class for most of CSE122. If you'd ever tried to sit through a lecture with that instructor, you'd understand.)
