I haven't played any of the games on Extreme (played them all on Hard, MGS2 with game over if discovered on because that's less frustrating) and I doubt I will for quite a while. I don't really want to replay these games just for the gameplay/stuff I can collect right now and I'm not sure if I ever will. I'd play 4 and Peacewalker PS3 HD before doing that, too.
