Steamleft is a webapp that aggregates and compares data between your personal Steam API and HowLongToBeat's data to estimate how much time it would take to beat your entire Steam library. It also provides hilarious alternatives for what you could be doing with your time, like reading The Hobbit or running across the United States a certain number of times.
