Super Mario Crossover

I am, apparently, not the only nerd that wondered what Super Mario Bros would be like if you got to play it as characters from other popular titles. Such is the thinking behind Super Mario Crossover - an extremely well done take on the original game but with the option to play as Simon Belmont, Samus Aran, Mega Man, Link, Bill R from Contra and, of course, Mario. Overall it makes me wish I had a USB gamepad of some sort so I could waste a large chunk of the day playing through it in its entirety.
