I am Kyle's self-indulgence

Ladies and gentlemen, I present to you the greatest flash game in the history of the Internet: Super Mario Crossover.

In this game, you can work your way through the levels of Super Mario Bros. with the heroes from a variety of classic Nintendo games.

Each character has his own attack abilities. You can shoot bad guys with Bill. You can stun and stab with Link. Furthermore, powerups like mushrooms and flowers bestow on the characters the ability upgrades they receive in their own games.

How awesome!
