Oh, the way the world is presented, the opportunity for discovery, the lack of spoon-feeding is a great part of the game. I love being dropped in the world without a clue and having to figure everything out. I love a world that's presented in little bits through atmosphere. But that's the setting, not the plot.

So far as the plot: (SPOILER)The entire game is fetch quests and "go kill this guy" quests. Then out of nowhere, it's like "I have this sword I can't unsheathe, and by the way you're the reincarnation of some guy who turned into the dome above Tokyo, so here go talk to this rock, he'll give you a cup you have to fill with liquid hope." What the crap?. There's no narrative, just weird stuff happens randomly, or something happens to force you to go from point A to B so you can find a new dungeon. There's no character development. I like the whole childhood friend arc at the beginning, but after that there's no interaction between people beyond killing or saving them.

Which is fine, not every game needs a good narrative. I still enjoyed the game a lot. The dungeon-crawling and demon-crafting parts are the main draw of the game, and I'm still doing it after 52 hours, so it must've been done right. It was very satisfying going from party wipe every 3 battles, to breezing through the endgame because I figured out how not to suck.
