Granted that doesn't mean it can't be a fun rip off.
I would not call it a "rip off" simply because the main gameplay mechanic is not the same. Smash focus on platforming and ring out, where PS all star focus on smash execution timing.
Its heavily inspired by Smash, but not to the point of calling it a rip off. It brought new ideas to the table with the Smash system and the Invasion levels.
Where a true rip off like Battle Stadium DON do not bring anything new.
