Know when you shoot a door on Metroid, and it take some time to open.. well.. I could understand why this happened on the NES and SNES.. but why is this still happening on Metroid Prime 3!? I always thought this was some kind of bug in the game, some times the door takes so much time to open that makes you think that it's stuck.. it's really annoying!! Did the programmers left this just for nostalgia!? I really can't understand this..
