it would be great if you could get a better stage building set more backgrounds and space and lets have some good levels desigh more like summit or the fire embblem catsle no side scrolling (stupid dk falls). they could also have achivements like (no need for smashing:ko a opponent without a smash attack 3 times) and others. I would like to see a new feature like a tag team mode online with firends or alone you can swicth between characters on your side and sometihing like marvel vs campcom where your side line pals hop in and like use an attack like there specials or tilt attack and they home in to your opponent. I would like them to bring back mewtwo with better specials plus a final smash where he fires a giant pshyco cut that you control like pikachus final but not so slippy and mabey megaman to make up for mml 3 legends cancel and since they keep making remakes on wii ware probably protoman too! lets change luigis final smash to a negative bomb luigi makes a huge bomb that sucks in a opponents and blows them up the bomb also rapidly gets hurt when cacthed that would be better and improve his fire balls they can charge up like lucarios aura blast but a little longer and faster with better range.
