I read Sal's post and the first one would kind of make sense in a Mario game. The second seems kind of odd, however.
Having creatures noises from the background is something they can do, but I don't know how that could actually add to the game.
They can easily make the Castles look cool in the Mario series, which, with what I saw in NSMBU, they are already trying to do. (The shifting backgrounds and that one really nice looking and creepy Art-like level.)
Don't they (enemies) already patrol an area?
A lot of what he has said seems to have been done in some way with Mario. Though, it's not 2D Mario, but more of the 3D Mario games.
Maybe that's what you should focus more on, HappyD, the 3D Mario's.
