If you are a child of the 80's you may remember the many fun games on the Nintendo: Mario, Zelda, Metroid, Contra, Megaman, Castlevania, etc. But did you ever wonder what would happen if the characters of those games ever swapped places? Well someone did, and the result of that experiment is Super Mario Crossover:
The flash game (you can play it in the link above) is the entire game of Super Mario Bros. for the NES. But now instead of playing only as Mario and you can choose from a roster of other characters complete with their own signature moves from their games. While the levels remain the same, the sound effects and music will change depending on the character you play as. And yes, all the moves of the characters remain the same. Suddenly, I realize Mario came ill-prepared to the Mushroom kingdom with his only way of killing enemies consisting of jumping on them or (if he was lucky) shooting a small fireball at him. Instead, he needed to bring a large spread machine gun (like Bill from Contra) or an arm cannon like Megaman and Samus.
Let's hope this begins a new trend of playable game crossovers beyond the videos previously shown.
