it's also annoying when a faction gets too powerful and starts to dominate the map...
Then it's up to you to calm it down. You could play longer games doing this.

Personnally I had a good amount of sieges all over the map during the 300/400 first days of my game. In fact the geopolitical situation has changed a lot. (Did you know Granata was an english town?

)
But starting from there, the siege frequency slowed down, an no one was occuring between day 600 and day 800. Then Glaschu became english, and another I-don't-know-where siege failed, so it seems to start again. And it was the same situation : battles, only looting...
But there is a problem with time in game, like 20 days truces during 20 weeks. We were discussing it few days ago, maybe this problem is related too?
For the marshall thing, so every marshall of every faction in my game is a woos?(Don't know what it means...) But sure they are fags.
I'll check controversies then...
