One thing I loved, the difficulty

[Serapy]

of course grinding is impossible in FFXIII, as you're Crystarium is capped off untill meeting certain requirements (like beating mini-bosses) leaving you with a bunch of CP you can't even use... despite this one minor flaw, i still love the game and consider it one of my favorites in the series, it truly feels like a spiritual sucessor to VII & X, only with an artificial limit to make it more difficult...

Grinding is possible... If you don't grind, you don't easily max your Crystarium at every certain point. When your Crystarium is maxed before each point, the monsters become a lot easier...
