Well that'll just about do it I think unless more content is released or I've missed something. I'm pretty sure I've seen and done all there is in this game save for the minigames in the extras menu, which, meh. But I've played through from easy to desperate, played through the extra dungeon, done the afterstory, and seen what I think are 5 different endings between the two stories. This is probably not the most impressive data anyone has ever seen, but I figured I'd post the final results of my playthrough of desperate here for giggles. I tend to grind a bit for things like the 3000 monsters quest and having all my status items at the same number because reasons. Plus I tend to try and be grossly overleveled rather than woefully underleveled and caught with my pants down.
