This is probably one of my favorite Smash clones out of all of them for now. Not only is the game play, the crossovers, and content, but for the encouragement for workshop support.

Ever since workshop has released during beta and since the making of this review, 5000+ creations ranging from new characters, stages, and more have been released, slowly and surely improving as time progresses. Not only that, but workshop is very optimized for categorizing different characters per series or creator and how it loads them up to not overfill the game.
