Ok, Qwepir, I want you to try and use your thinking cap to actually process every word I'm saying.
http://steamcommunity.com/id/nickelob-ultra/gamesPlease look at the "Recently Played" tab of my games list. You will not find Call of Duty listed in there at all because I have not played it within the last 2 weeks.
If I were to use your logic on your games list, that's like saying you obviously play Half Life 1 all the time because you have an amount of time logged into it.
Amount of time played in a game total =/= amount of time played in a game recently.
Seriously, it's not rocket science. I can guarantee that at child half your age can understand this rationality 100%.
