I've just started playing Metroid Prime 1 on my Wii. I'm trying my best to scan everything, but scanning both sides of the doors & just all the other random crap gets kind of ridiculous. I just wanted to know if scanning all of the random stuff is necessar, or if I'm only suppose to scan enemies & important stuff like that. & if I do have to scan all the doors & boxes, that just tell me pointless info most of the time, what do I get in the end?
