I'm enjoying DQ 9 a lot, it's a pretty fun game. Although so far the story is mode is pretty easy, it does have side dungeons with hard bosses, it also has downloadable quests, while you can download them anytime you unlock the Wifi shop, a lot of them seem to only be completable once you complete the story. A new downloadable quest is added every friday i think. They wifi shop also has special stuff you can buy, some are pretty rare items i think.
