Here are some websites that I think are related to video games and that I think are pretty cool. I'm sure there are millions more out there, but at least its a start. I'll try to edit the blog from time to time with more links if I find any that are worthy.
http://www.replacementdocs.com/
Bought a used game and missing the manual? Check here, you'll probably find it in downloadable pdf format. Literally hundreds of manuals, some from systems long ago.
http://www.nintendo.com/consumer/manuals/
Nintendo offers some of their manuals in the support website, most have probably already been uploaded to replacementdocs.com though.
http://www.typenow.net/themed.htm
This website contains various fonts for you computer from films, music, and video games. Pretty cool if you're trying to make a banner or wallpaper.
http://www.vgchartz.com/
This website tracks various statistics on hardware and software sales. Some people criticize it for not being accurate, which it may not be, but overall I think its a pretty good guess.

http://en.wikipedia.org/wiki/History_of_video_games
Wikipedia is probably the best information source on the internet. If you want to know something, check there first. Their video game topics are pretty sweet, especially the history of gaming for all you youngsters who don't appreciate how far gaming has come.

I need something with some story and depth to it. But if that is the type of game for you, here are a couple links for you to game for free.
