lol perfect response

Where do they get these testers?  Must be one of the runner up prizes at the special olympics.

In the Left 4 Dead commentaries, they say "We then invite friends and family to come over and test".

I think that just kind of said, "Piss off the ones I don't know, let my children and my grandnanny's niece to play".

ValvE has a bad habbit of listening to playtesters. They removed a lot of awesome things from a lot of their games, because of their playtesters. (Namely the Left 4 Dead series)

Nonlinear levels. ;_;
