Arguably by 2012, Valve was already transitioning out of the game development business and into the services business. Team Fortress 2 was already out, Left 4 Dead 2 was already out, Portal 2 was already out, Counter-Strike: Global Offensive came out in the same year, and Dota 2 came out the next year. Really the only things that have been made since that period are Half-Life: Alyx (2020), Counter-Strike 2 (2023) and Deadlock (TBA).
