But not enough to figure out the world - you need to make your world was not internally inconsistent. Not stopping to think of its history and laws.

Heart role-playing - role-playing system, economic strategy - ways to win, and events of a collectible card game - the order of moves, the rules of rotation and/or removing and putting some maps, tactical combat game characters and order of damage, etc.
Consider the rules. They are usually "tied" to the mechanics, will represent the principles of interaction between the players, the laws of the world and the system of tunnels. Consider how to change the rules.

If the game was a great success, can try to offer it to publishers. Many manufacturers of Board games are looking for talented authors. Good luck and inspiration!
