Dragon Quest IV impressions at RPGamer.

"From a North American perspective, you'd think Final Fantasy would take precedence over the Dragon Quest series in terms of games slated for ports or remakes. But this is Japan, and in Japan Dragon Quest reigns supreme. Even during an interview with the producers of Infinite Undiscovery, they admitted a liking for turn-based games like these. So, if you think of it like that, then it should be no surprise that Dragon Quest IV DS was available to play, and again it's no surprise that the DS was the console of choice, given that everyone and their grandmother over here owns the console."
