p.s. What about the "Order of Chaos" expansion?
By default, games are played without the "Order of Chaos" expansion, but you can agree to play with it if you wish. Any problems that may arise from using it will be the responsibility of both players.
Diamond is a very interactive map, so there could be a lot of issues with "Order of Chaos". I wouldn't recommend it =)
Also, one more thing, since there is trading involved, redrawing is allowed. Should this be explicitly stated in the rules, or is it already understood?
