Ever wondered what it would be like to play the classic Super-Mario Brothers NES game using another character?  Well newsgrounds.com creator ExplodingRabbit has released a flash version of the classic Super Mario Bros. title, Super Mario Crossover, that allows you to use with Simon Belmont from Castlevania, Link from The Legend of Zelda, Samus from Metroid, Mega Man, and Bill from Contra.  All characters maintain their special weapons and characteristics and the game even introduces a few new character features when they interact with the Mario Brothers game environment.  Bill gains a ‘rapid-fire’ ability when he eats a mushroom, Samus can plant bombs when she is in her ball form and even the music changes for each character.  This flash game offers the perfect distraction for your 2pm post-lunch food-coma, and may make you wonder why you ever ditched your original NES in the first place.
