OKay, okay, okay, I know that the Xenosaga games were not made by Square-Soft, but Monolith part used to be Square-Soft, and this is general gaming so whatever.
Is there anyone else who agrees that Albedo was the best villan ever? Firstly, he had a reason for his insanity. It was when Rubedo (Jr.) broke the mental link with all of the U.R.T.V.'s that he became insane. His objective was revenge. Also, his voice, more importantly his evil laugh. It was the best one I had ever heard. Also, the one thing that made me like him the most was the scene with him and M.O.M.O. That was probably the best thing I could see a villan do.
So, I just had to say my thought about him being the best villan. You can disagree with me if you want, because I do not really care.
