I can't tell you how much I played it since I have no numbers, but Master of Orion 2: Battle at Antares takes the crown for sure. In the 20 years I'm playing the game I probably amassed over 1000 hours of gameplay
And according to Raptr, I spent over 150 hours on Freecell - though most of it comes from occupying myself when websites takes too long to load (and often the case here in the forums btw)
