I barely remember Super Metroid as I never owned nor beat the game, but didn't you aim up, down, forward and backwards to hit enemies, not just face the direction and push a button.
I don't remember Super Metroid having auto aim. I could be wrong, but I really don't remember the game having it.
Other M might end up playing great and being really really fun, but just watching the video, I'm a little less than impressed if the game does all the aiming for you out side of the FPT(FirstPersonTurret) mode.
