It's a stubborn one, isn't it? I hate that it insists on auto-correcting itself after a second of not touching the right analog stick. So many times, I'm hiding in a box/barrel watching an enemy move by, and the damn thing changes right when I get up to move. It bothers me that the camera's movements aren't predictable; if they were, no matter how illogical, I could at least plan around it. What was wrong with MGS4's setup?
Beaten it three times now, collecting the other things, trying to get good scores. The Fox blade definitely should be saved for after you've beaten the game, since it utterly decimates non-UG enemies. Pairing that with the pole-arm makes for some crazy-looking on-screen demolitions.
