I saw Enter the Freeman on Geeks are sexy and so wanted to gather in this post a few fan made Half Life movies. And I think there could be more, but even there are absolutely awesome.
Half Life was the first game that could run on my PC and still has great graphics. The story was also well thought of. I might even try to play the remake of Half Life. Enjoy.
