-more levels for SSE
-better cutscenes for SSE
-more SSE enemies
-more stage builder items
-more battle stages
-more items
-more characters
-Story mode
-Isaac as a playable character instead of assist trophy
-voice actors that do more than grunt. Because Snake, Wolf, Fox, Falco, Pit, and Zero Suit Samus are the only people who actually speak
