Steam Most Game Hours on Steam?

Here is my top 5 played games in order on my alt account. Counter-Strike: Global Offensive 2,092 hrs on record, Path of Exile 82 hrs on record, Killing Floor 54 hrs on record, Shock Live 49 hrs on record, and Serious Sam Fusion 2017 (beta) 11.7 hrs on record. Another thing is that on both accounts CSGO is the most played and second most played game is Combat Arms or GMod.
