Lightning Returns: Final Fantasy XIII

linked the game to FB, but no garb for me, please tell me i don't have to link it to twitter too

I don't think it actually tells you that you unlocked it, there's no reward message or anything. But as long as you published the Battle Rewards somewhere, i'd imagine that if you linked that same account to the full game, you'll get the garb.

And I liked all the characters in the original FFXIII. I thought the characters totally made the game for me.

Wasn't that big of a fan of Lightning, but she was a good strong character who rallied the party like a good leader, and her moments with Hope and Snow were great.
Sazh was great as comic relief, and so his breaking point with Vanille was especially good characterization.
Vanille herself was a much deeper character than she initially appeared, and behind the annoying moeblob exterior she was an interesting character. And it was good to see her develop from a coward who fled from her destiny to someone who was willing to sacrifice herself for her friends, after seeing how determined they all were.
Hope was a good character, I thought his desire for revenge was childish and immature, and I think that was the point. That he got past that, got over his issues and kept on fighting was really good character development.
Fang... I think the fact she didn't join the party until much later kinda left her to get overshadowed by everyone else and their character development, but I suppose she learned to trust in others.

The story and characters in FFXIII were amazing in my opinion, something that I thought the sequel lacked (with the exception of Caius)
