It used Super Smash Bros. Melee as a foundation and did its own thing. Melee players will feel at home and new players can get up to par with the old balls through great tutorials and explanations.

theres 2 options with this game, either you play the original without mods wich is still a very good game or you have the untitled goose, matt from wii sports, sans undertale, and barack obama fight on top of a mcdonalds 10/10 game
