X-Men

I would keep the layout, art, music and DMD animations. I would also keep the basic backbones of the rules and game progression.

I would change the Wolverine figure, going with a more Walking Dead type bash toy that would be universally positions on all models of the game and allow room on each side for the shots to the left and right of it. I would also clean up all of the modes, ditch the craptastic callouts and actually have them record some negative callouts so the games wasn't telling you what a great job you did when failing modes.
