How to check the total time played on a game?

Is there any way to check exactly how much time you spent playing a game? I see a lot of people on here saying they spent x amount of hours playing a game before they beat it. I was just wondering is there a way to find out or are those people just estimating? I do know that certain games actually telll you the total time spent playing, but I was wondering if there is a way to find out for all games...

well there is no universal way like you said some games show you though. Actually you can use raptr which will keep track of how long you have played.

This is one of the reasons I actually like the WII. It keeps a log of your time playing any game or doing anything on the system

Raptr is the best thing in the world. Click Here for the site.
