Is this game worth playing?

[Sephiroth]

I didn't like the story that much, but it is by no means bad, it just doesn't feel like a real continuation to XIII.

Other than that, everything is superb, an improvement over XIII's sad gameplay.

Yes, it is more like a completely new chapter but that is no wonder. They needed to begin a new life on Gran=Pulse.

I tell you, get Final Fantasy XIII-2. I love it.

"It's so bad and full of plot holes, inconsistencies and retcons"

Except it isn't and just not understood, like Final Fantasy VII and others by many in this forum and everywhere else.
