Did you grow up playing Super Mario Bros? How about the Legend of Zelda? Megaman? Did you ever imagine what life would be like if Link (from Zelda) could run around stabbing those stupid goombas with his sword?
Now you can bring Link into Mario world, and stab away. Thanks to Super Mario Bros Crossover by Exploding Rabbit.
I played with Link. Powerups upgraded his sword. Playing Mario with the Zelda theme music is also kind of cool.
