I recall having to quit Illyriad [1] because the PvP politicking was so intense it was undermining my ability to function IRL. That's pretty common in that game.

There's a couple of bona-fide dark patterns in that game, but the developers definitely tilt towards serious gaming, and overall the game is the opposite of cow-clicker addictive patterns.
