Many gamers have fond memories of the original Super Mario Bros. In fact, I bet a good number of you even remember vividly each stage and where the secret boxes are. A clever programmer by the name of Jay Pavlina has created a tribute called Super Mario Crossover. In this version, you can choose to play not only as Mario, but also as characters from other games such as Metroid Prime, The Legend of Zelda, and Contra.
The best part is that these are not just skins that replace the original Mario character as they move, jump, and shoot just like they do in their own games. So, for example, Link from The Legend of Zelda has a sword and can even throw a boomerang--let's see Mario try that! It's an amazing tribute to the NES era--try it out for yourself at Newgrounds.
