Surprisingly, Valve’s Portal (part of The Orange Box) did run quite well on my low-end PC. While some people complained that it is too short, I am actually happy with the fact that you can play through it in one or two sessions. I just don’t have as much time to play games as I had as a kid anymore. However, Portal is actually longer than you’ll think at first, and it does a good job in playing with your expectations through the whole game. The puzzles are mind-bending and challenging, but never unfair. A slight motion sickness might occur, though. I am also going to spoil that the end boss is really really cool. But you’ll properly have played it already.

First off, I would like to say how much I enjoyed the Understanding Games series. Even as a hard core gamer your games put everything I play since the in a new perspective. Second, I was just checking out your website for the first time an noticed you had a post on Portal. I love this game and just incase you didn’t know, my friend and I found this, In one of the “unkempt” rooms there is a radio. If you pick it up it will play the song “Still Alive” from the end. This is in the level after you have to destroy the companion cube. Please finish some more games and, specifically, please make more Understanding Games. Perhaps you could make an Action Script tutorial. Sincerely, Nightingale. THE CAKE IS A LIE!!!
