In the meantime, we can always go back to the old-style PBM. I admit that the WotS-type of PBM has kind of shut out the sucession games, and deservedly so since they're more immersive, but I believe that ETW is naturally suited to people reigning for a certain period of time (10 or 20 turns - this would adequately be suited to a Constitutional Monarchy type of country), controlling every aspect of the game, and then passing it onto the next player, writing up a detailed report for everybody.

The last such PBM before Will of the Senate came out, Re-unification, is an excellent read of a bunch of players doing the Western Roman Empire campaign for BI and is what drew me to the Throne Room in the first place. I'm sure that we can produce a couple of PBMs of similar quality while we work out the kinks and either CA or a mod gives us better material to work with.
