Online Video Game Player
I just recently got an email from my uncle, and in it was a link: onVGP. This site contains 1000's, yes thousands of old video games, anywhere from Super Mario Bros. to Zelda to Sonic. It is still in Beta, and isn't anywhere near perfected, but if you need a quick or extremely long fix, this is the place to go. Not too many people seem to be visiting this website, so spread it around, as it can provide hours of fun. I'll be putting it in one of my link sections later too. Have fun, but not at school/work! Fun is forbidden!
