Ok let me translate:
"We came to this business to make the most money with the least amount of work, so, we stick to the PC and 360 because they are easy to program for and we are too lazy to learn any other way of programming. I mean if we could have an engine that could just do all the work for us we could just sit on our asses all day and count the money."
Did that read like I was pissed off at Valve?, All kidding aside I think Valve should just stick to PC, they don't support 360 as much as they do PC, they just dumped code and forgot about it. I really hope other companies aren't as lazy and think of themselves as all high and mighty.
