From the introduction:
Noble Houses is meant to be played on the internet, through the use of a forum or blog. Each player has their own unique account; none are anonymous. Messages are posted in a public area or sent privately to various players. They may also be sent privately to the "Bureau", a neutral party that oversees administrative affairs.
The game utilizes two variable scores - Money and Resources. These are traded or spent to gain influence in the narrative process. The game proceeds in structured turns. At certain points, a "complication card" is played; usually, these influence the turn structures.
