The broken mess that is the Capcom Vs. games
These games need little introduction, to cut the story short this type of game need not be a 2D fighting game but rather a open world RPG similar to the anime game One Piece Odyssey. This game uses turn based combat and it works well without being too difficult for the player. This way a real story can unfold unlike the Vs games garbage storylines that are essentially meaningless. Broken fight mechanics replaced with tried and tested turn based combat with a little QTE for some stylish action. This would also give the developers the chance to really flesh these Capcom & Marvel characters out, which is the real draw to these games anyway.
