Thanks for your ideas and thoughts, I get to you back later.
I logged in now to say..
I told earlier slower game should have smaller KD-s. That was bad idea - should do opposite, instead - have bigger Kingdoms there, like 40-50-60-75-100 members max.
Because game is slower, people log in less, cause they know there are liek 6h turns - for example - and attacks are slower and so on. To get excitement, more to the game, there should be some activity in kingdom - talks, chats, what so ever, if more people, then it goes more democratic game and depends more about mass oppinion, not too monarchic - because to take it with logics, one monarch cant micromanage alone whole kingdom then. Also can get faster battle-activity to contra, if needed. Monarchy is right rule, but you know - in big KD there must be really some generals extra to get things done, cause in bigger KD more people move around, change their kingdoms, defect - and to remember all 99 members who and what they are.. it goes harder.
And no recruits or invites, all joins random, with old rules, collapses of provinces maybe in 2 weeks?
