I've beaten story twice, so naturally, I'm on story++ by now.

Really, the only difference is that the enemies are stronger compared to the last time. The game actually gets easier as you go on because by that time, you already know what to do.

Anywho, all my peeps are at least lvl 85 by now. Plus, all their equipment is the highest I can get for them with three stars. Hp & Sp regen rocks! Though I have yet to figure out what lady luck does...

Anywho, if you play the game through three times, it'll last you pretty long, a total of at least 30 hours.

Not to mention you have multiplayer mode, which is what I think they were trying to emphasize in this game more than anything. Only thing that sucks is you can still get hit in pause menu.

So no, it's not too short. Specially if you take the time to find everything.

When you're ordering stuff, push the 'added material' button.

It'll let you choose a gem to use in synthesis. You won't really know what each gem does until the item is made, though.
