I'm playing Dragon Quest IV right now and, while it's a solid game, boy is it making me appreciate a lot of the advancements in VII they showed during the Treehouse gameplay. Even beyond the huge step up in visuals (which is to be expected when you're going from a DS remake of an SNES game to a 3DS remake of a PS1 game), having a robust job system is a game-changer for games that are this dependent on grinding.
