For the record, I finished Final Fantasy 13 yesterday and it was every so satisfying. I liked the game a lot more than FF12 but that was more due to the story than anything. The ending of the game was pretty good. It wasn't as good as Final Fantasy 10's ending, which rests pretty much at the top of my list of all time best endings to a game, EVER, but it was hitting a lot of the right notes and was one of the happier endings to a Final Fantasy game, all things concidered.
I've got to try to resist the urge to go back and grind through the post-game content. I have other games that I can put that time and energy into! Or, you know, I could read a book or something.
