I'm looking for something like SSB that can be played/emulated on PC. Can All Stars Battle Royale from PS3 be emulated?
there are already similar games on Steam http://store.steampowered.com/app/291550/Brawlhalla/ http://store.steampowered.com/app/411480/BATTLECREW_Space_Pirates/ http://store.steampowered.com/app/263720/Brawlout/ http://store.steampowered.com/app/261180/Lethal_League/
I think there's also Rivals of Aether. That being said, these are usually easier to play on a game controller rather than on the keyboard, so think about getting one if you don't have one already.
