Super Mario Crossover Blows My Mind

My inner child is giddy with glee.  A developer at New Grounds has recreated the entire Super Mario Bros. game and made it playable with characters from old NES games.  You can play the entire game with Samus, Megaman, Simon Belmont, Bill (Mad Dog) from Contra and even Link.  Powerups grant abilities for certain characters like charging the megabuster for Megaman or spread for Bill.  Just awesome.  You can check the game out here at New Grounds.  You can thank me later for that smile on your face.
