In a report by Steam Spy, we’ve learned that Steam users have been playing Valve-developed games quite a bit.

According to the Steam statistics tracker, since the beginning of this year, Steam users have spent over half their combined playtime on Valve-developed games.

This kind of makes sense considering how massive games like DOTA 2, Team Fortress 2, and Counterstrike: Global Offensive are, as they frequently top the Steam’s player charts on a daily basis.

Do you use Steam, and or play Valve-developed games? If so, how often?
