You have to say VALVe is one iof the best if not the best company in the world... i remember Gabe offering protesters into Valve HQ and bought them Pizza and let them play some beta for a game for a few days. Damn...
I know its not gaming but i believe Pixar studios is the same style of work place, i watched a behind the scenes video and they explained what it was like to work there it sounded incredible.
Was that the one about John Lasseter. I really am a huge believer in the notion that your environment has a huge impact on your ability to work and what you're capable of achieving.
It's nice to see that not all of the huge companies are tyranical entities where creativity and working conditions are given a backseat in favour of being able to churn out stuff just for money.
I'd like to see more companies follow in the footsteps of Valve and Pixar. Work should be enjoyable and not a chore.
Still as people have said, it must take some getting used to if you've worked within a very heirarchical environment for all your life.
