Read the blog, came up with the idea!
Proposal on the map! To make the map need paper and Coal, when viewed tertorii card will complement and coal run out! Set on your map you, your home, your friends, mountains, forests!
Maps can not be sold or transferred! it is cleared when transferring =)
Although if someone will spetsalno run across the map and open (to draw with charcoal) and then sell ...

P.s I know that the card will not do soon, but I just offer the option
