I was addicted to Cookie Clicker for a while, as I thought it kind of had a story. It did, in which everyone loses their minds. Hm. I do have Idle Champions of the Forgotten Realms and Fallout Shelter 3 downloaded, but those aren't really tycoon games. Personally, though, I played Cookie Clicker while working where I would have gotten in trouble if I actually played a 'real game' but I had plenty of time to occasionally click or watch my numbers go up. So for me, it was just minor entertainment at work and stickin' it to the man.
