Because when have you ever before played a game in which you're a mute, ugly-as-an-ass test subject with metal springs on her feet with a gun that shoots paradoxes being ordered around a sterile test lab by a robot with more than a few screws loose?

Team Fortress 2 was the best thing in Orange Box for me, but Portal was amazing as it was so different as you had to work out puzzles without using a gun like penumbra in that way
