That is a good question.

What I was thinking invloved "gametime."

Various games have gametime/realtime ratios. Birthright would need the same thing. One week in real life constitutes 1 month BR time, which would mean 1 domain action. Or maybe 1 week would constitute 1 domain turn with 3 actions.

This basically means a ruling scion (of a guild, temple, law, or source) would have one week to do any domain actions. This would encourage activity and punish inactivity.

The setup for this would involve the guild structure of other MMOs, but slightly modified, of course. Say we're talking about a realm. The GM of Guild X would be the ruler of Realm X. The members of the "guild" would just be members of the "court." For Temples they would be in service to the church, as priests, guards, etc.

If the GM is lax, the realm suffers and the scions of the guild would have the option of deposing, or replacing him/her.
