if that's Panzer's idea of free look, they're... WRONG.
I'm talking free look as in the usual look at your environment at practically any angle that's inherent in FPS games and the first-person views in the 3D Zeldas -- that is, you decide what the camera looks at, which isn't the case at all in light-gun games. Free look doesn't make sense in games that are truly on-rails since your body would continue moving forward uncontrollably while your gun and eyes could be 180-deg the other way, while you can't see what you're walking into. In the back of a moving truck, it'd work, but as a walking person? Nah I fully expect you to trip and fall down a flight of stairs and die.
But free look makes sense in killer7's context. Walk forward when you need to (w/ quick turn around option). Free aim to target vital points when it's time to get down to bizniss. No blind aiming or awkwardly running into walls and furniture, completely unlike the old RE games. AND no pointless, awkward running into the stage scenery to look for hidden items that likely don't exist, avoid constant "There's nothing unusual about this" type of messages.
