I suppose that's what happens when you take a laundry list of fan complaints and try to fix each one of them while ignoring the own "identity" of your game.
"You want towns? I'll give you a fucking town and arbitrary quiz exploration, you ungrateful punks! You don't insult the creative prowess of Lord Toriyama-sama just like that and get away with it!"
I said this before the game came out, but I always felt as thought they were just throwing everything they could into this game including the kitchen sink and the result just didn't seem cohesive in general. And when I played the game, that feeling was retained. The game truly did lack its own special sort of identity.
And in an effort to appeal to everyone, including those who thought that the original XIII was too difficult, they made the game way easier and added an Easy Mode... but didn't adjust the difficulty for those who were more than fine with the original XIII's difficulty.
That's the thing that disappointed me the most. Fix the balancing and maybe I'll have fun with it, because after a while into XIII's late-postgame aside from killing turtles, I had fun with the game's battle system after going through and timing attack animations, syncing party+enemy attack animations, knowing when to Optima Change, learning about ATB cancel, etc. And the enemies in XIII put up a decent fight to boot. The incentive was there to think of different ways to take enemies down with defensive or offensive Optima sets after you've done it for the first time. In XIII-2 the incentive isn't there except for the possibility of a rare drop... which you don't really need.
That doesn't mean that stuff like Change Leader, removing that asinine camera pan+extra animations during an Optima Change, and loading/saving Optimae isn't welcome, because it totally is, but I just felt like CSB just wasn't supported at all in FFXIII-2 like it was in FFXIII. Difficulty, balance, and scaling enhances CSB. ...and I don't even like CSB all that much...
Edit: Hahaha, I'm always stuck at the bottom of the page. This is great.
