Curious what everyones most played game is at this point? If you do the majority of gaming on Steam you can use Steamdb's calculator to let you know what games you spend the most time on. Plug in your public Steam profile and then sort by hours. It also calculates your Steam account value based on sale price of games but it doesn't take into account bundles or sales.
According to my report above my most played games on Steam are Terraria at 170 hours, Borderlands 2 at 54 hours and Prison Architect at 36 hours. That's pretty impressive but I bet I've clocked way more time on Zelda: Link to the Past and Hearthstone is fast approaching one of my most played games. Hopefully Blizzard lets us see our time spent in game at some point.
What game have you spent the most time playing so far? What does Steamdb say about it?
