Before any one ask... I do not have a gambling addiction. I just though it would be nice to have a place were we can gamble our crowns away in which are gear doesn't factor in to our possibility of winning (lock down). It would be a great addition to haven expansion and would add more variety to the game. The casino should allow knight to gamble with other knights or against computer (maybe represented in the form of a monster like a gremlin or devilite).
The casino could include game like poker, slot machines, fortune wheels and a bunch of other casino game I don't know.
