You may not have heard of this little gem. It suffered from poor marketing in the US but still sold VERY well. It was made by Square Enix for the DS. The plot revolves around the main character, Neku, being trapped in the Reaper's Game, an alternate dimension layered onto our own where those who have recently died try for another chance at life. More than that, I can't say. However, over the course of the game, we see Neku go from being an arrogant, self-absorbed, anti-social dickbag, into a brave, thoughtful, and even friendly protagonist. And they do it well. It isn't one event that just flips the switch on his personality. You literally see it happen over the course of the entire game through the little things he says and does.
