Really, it could be that i am an adult, but thi game was ridiculous and embarassing. Packed it up, and sent it back within a day. Not worth the rental.
Like any other Nippon Ichi game, this game is such a time-sink in terms of grinding. Its your typical linear JRPG, except rushing to the end gets you bad endings. You have to actually grind for a while to unlock a good ending. It's not a good short-term rental. Just buy it if you're into mindless repetitive grinding. Battle system is kinda fun, but all their attacks look generic and gets repetitive quick. You'll end up looking at the button patterns more than the actual fight.
