Being the useless basement dweller that I am, I couldn't help but wonder just how much time I had already spent being a burden to society (aka playing games). Since it'd be quite difficult to account for every single game I'd played in my whole life, I thought I'd make it easier and focus solely on the hours logged by Steam.
After a quick search I found this website which does all of the hard work for you. Just put in your SteamID and it gives you detailed info on your total play time as well as more stats than you'd ever need to know.
Turns out I have 1935.8 total hours on Steam, far more than I'd like to admit.
I thought it'd be fun to compare, so please post your results below.
