I've surpassed 30 hours in Mystic Chronicles for PSP via my Vita. Definitely meaty for a Kemco RPG. I'm pretty sure I'm in the final dungeon now (outside whatever post-game dungeons there may be). I've completed every quest currently available, but I could do more stuff in the coliseum. I hear some people grind a lot for the final boss, so if I hit a roadblock, I guess I'll do that (though I can't remember if coliseum battles give EXP). But I don't often run from battles, so maybe I'm good. My party members are around level 60, and they're gaining levels like crazy on the enemies I'm currently facing. This seems like the most labyrinthine dungeon yet. I hope I don't miss any treasure, since I am actually still lacking a few Training Books (but for all I know, they could be in the post-game).
