Cartographers Heroes is a good sequel, improving on Cartographers in many aspects.
Using many of the same rules as the the prior game, Cartographers Heroes introduces the titular Heroes, new Monsters, new Edicts, new Skills in a mini expansion and 3 brand new maps, each introducing new rules.
Cartographers Heroes introduces numerous dynamics, and requests more expertise from the players to manage everything that is going around, with harder-to-meet Edicts.
