I have to say Xillia, actually! (Jude's side at least.) Not only do I love that (most of) the antagonists aren't actually villains (or, they're not text-book villains, at the very least), and they have such a definitive role to the plot, but because I think it's very interesting! I like how it's different from the other games, too.

The runner-up would be Vesperia, though, mostly because it's my favorite game.
