Final Fantasy XIII.
Do I really need to explain? Really?
Okay, fine.
Vanille, the fact that all the more interesting parts of the story are buried in the Datalog, Vanille, the fact that the ending doesn't make any kind of sense unless you read the Datalog, Vanille, the way you don't have the full battle system open to you until your 2/3 of the way through the game, Vanille...
I could go on, but I believe I've made my point.
Vanille...(*seething*)
