I found this cool little thing for steam the other day. Basically, it tells you how long it would take to beat every one of your steam games without stopping.
http://steamleft.com/It would take me 1 year, 60 days, 13 hours, and 36 minutes to beat all my games without stopping, and in that time, I could watch the entire Star Wars series 768 times.
How long would it take you guys to beat your whole steam library?
