It is possible. Civ 5 had an option to display game-play time. This was all I needed to avoid really long sessions. It would be great if all games had this option, as most games go full-screen obscuring the system clock. The alternative is to put a physical clock where you can see it by only shifting your eyes. That said, I don't play games anymore. If I did try them again, I would want a visible clock.
