Atlus has really put a lot of polish into this game and into its translation. If you like RPGs you should definately picks this up!
It's some kind of hybrid between japanese school life where you have to make links with people and unravel their stories while trying to reach the top of a tower, Tartarus, only appearing during a special time of day, the Dark Hour.
I ended up taking 80 hours to complete the main quest on Normal, sometimes it was downright too easy but other times I barely even made it, quite a challenge! I still have to do it in Hard mode and start the additional 30 hours quest...
Unquestionably worth buying!
