Clash of clans, WIP. I don't even play the game (Dominations if I want to waste time), but something about the absolute expendability of your troops - I mean, for goodness sake, you don't get them back after the battle ends even if you win - seems relevant to this site and its interests.

See: https://www.youtube.com/watch?v=oVqyrjK9ASo&index=8& for the dark themes you can dredge up from a simple mobile game. Countless millions, all for our amusement.
