Enjoyed the game and completed, I think, all of the (minor) side quests on top of the eight character stories. Didn't get around to doing any of the postgame stuff. I have no idea what's there at all. I did do the secret class fights. Those were great.
Terrific music and combat, solid writing but slipshod plotting. I don't mind, and even enjoy, as an idea, that there are eight unique character stories that do not connect to one another, and that the party forms out of a need for mutual support. Really, what bothers me the most regarding the story is that the scenarios and character beats are not paced out well. The episodes are truncated and the storytelling is awkward for it. Regardless, the game was simply fun to play and I appreciate what they were striving for. I'm in for a sequel, and I think they'd improve on the common complaints.
The side quests being open ended and revolving around character talents was pretty cool and I'd like to see something like that explored more in the sequel.
