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.
Yeah, at 7k+ hours, my Dota time dunks on pretty much 90% of the people in this thread. And I'm still not tired of it. It's a daily ritual type of game.
Thing is, the time I put isn't even close to the time of several of the people I've met.
