Fantastic Story, Great Game And So Much FUN!!!
The only drawback I can name is the length of the main story, I finished in around 8 hours and I couldn't help but feel sad, I just wanted more. After two more play through's I still feel sad when I finish as I just want to stay in the world that Valve created. I would buy Portal 2 again without batting an eyelid, this game needs to be played and shared with all your friends. My hat goes off to the team at Valve, this release is sensational.
