The only thing turning me off from what I hear is the ending is only finalized in the DLC. I might just wiki the DLC and catch up on what happened in it for Lightning Returns.
Lighting Returns looks sick. Lightning is my favorite character in FF13 so far (although some don't like her), and the combat is already so radically different from previous FF games that I'm open to the change the series is making.
