I love love love the style, believe it or not, but agree that it lacks a lot of true replayability. Only desire I've got to push through that again would be to go for the 100% completion, but that's something I can work on in bits and pieces between other games. I thought the game was quite good, but there's little room for variance.
I will go through it a second time sometime in the future, but no rush. (I do need to finish getting the rest of the endings for XIII-2 before LR, though...)
