Super Smash Bros. Finale

Super Smash Bros. Finale is the supposedly last game in the Super Smash Bros. installment. It would be released after several sequels were made to Brawl. The game would play very similar to the past installments, but have several new content.

Characters
The characters in Super Smash Bros. Finale would obviously be plentiful. There'd be 300 playable characters in the game. I may not even get to listing them all. But I suppose I will.
