VNN (Valve News Network) has recently uploaded a video detailing the history behind the immensely popular game Portal. The video travels through the humble beginning from a small group of developers all the way up to the massive success the game has become.

It is very interesting to see how Portal started out by using the assets of Half Life 2 which, as you can see in the video, give the game a much more dreary and spooky atmosphere, as opposed to the high end scientific look that we are all used to. It’s also pretty cool seeing all the different textures for the portals themselves as the game’s entire art style progressed.

Personally, I am glad that the art style was changed, as the very clean scientific textures suit the story and atmosphere much better. What do you think?
