Honestly , it ' s likely more than anyone has put into GO . I don ' t want to use Source , because it ' s not nearly as popular as the original CS or GO , but CS has been out for almost 20 years , so there ' s no way I can say I ' ve played CoD as much as anyone ' s played CS in general . I ' ve got roughly 1500 hours in CoD 4 , and that time played is literally just in matches themselves . Lobbies and menus are not counted for Call of Duty ' s time played stat , whereas on Steam , every second with the game launched is counted . I ' ve got roughly 1500 hours in Modern Warfare 2 , roughly 1200 hours in Ghosts , etc . , etc . All tallied up , I think total time played has got to be around 68 k hours . <| sep |> I dunno , I ' m personally pretty shit at slide puzzles .
