In the game central instead of direct games, you can have the rails take you to different made playsets (Like MU or Incredibles including a felix and sugar rush set)
If you do that you could have a mission where you have to travel through all rails to get a collectible from each set (Like he did with the cherry from pacman but disney stuff like for the Incredible you have to bring a omnidroid or a toiletpaper gun from Monsters University) once you get all the collectibles back to game central it will trigger the mission coin to appear! What do you think? Of course there could be bonus stuff like you have to get a trophy from the sugar rush playset so you race in a track. Or you have to play a paintball game and win to get the toilet paper gun from monsters university playset.
