I discovered today that my most played game on Steam is Astronner with about 500 hours, and my second most played is Surviving Mars with about 500 hours.
I'm over 10k hours on FFXIV, been playing since launch. Could get an exact answer when i get home. Next closest is Skyrim with around 1,500.
Edit: it's over 14k hours, more than 584 days worth. It'd be much more if I had more time the last two years but I can't do much than dailies with a 15 month old!
In which game did you spend the most hours?
