Ehh who knows? People come and go in the gaming business. They're contractors for the most part. Or MAYBE it has something to do with profit sharing. Valve has made a ton of money the past few years. With no news of an expansion in their studio department, one has to wonder what the hell is going on.
Valve's gotta get going on the new games or i sense the high road for others as well. This 1-2 games a year biz has gotta change. Where's Half Life: Episode 3? Where's Portal 2? Where's the fix for the servers? How about a new revamped HL2DM game which combines L4D and HL2? We've been patient Valve common. Speaking of Episode 3, i hope it has 4 player coop.
