I liked Mark of the Ninja's ending, even if it came completely out of left field.
Also Rule of Rose. The last third of the game was kind of sequence-breaky considering the chapters leading up to it, but it tied off its ends nicely and let you kind of write your own ending with what was left. If only the gameplay wasn't so horried.
Well, I only go to two other forums: The Escapist (deal with it) and my TF2 clan's forum. Pretty much no one uses their own picture there either. I thought about putting myself on my Escapist account once, but it just seemed kind of vain.
