Oh man. I get it, retirement is coming and all, or just wanting to move on, but the more old guard we lose, the closer to the bad times we get. I'm dreading the day when Valve is nothing but new blood. If you want some insight into what that will look like, look no further than Blizzard, Infinity Ward, Rockstar, DICE etc. Basically any team that's lasted long enough to keep the name but lose the soul.
