How often do you want to see states of war between players?

[econ21]

This is just an informal poll to gauge people's views about PvP play in KotF. How often would you like to see players in a "state of war" with other players?

Explaining the categories:

Endemic - multiple wars, almost all the time
The norm - at least one war to be "on" during a session (10 turns)
Common - around one out of two sessions to experience PvP wars
Uncommon - around one in three or more sessions to experience PvP wars
Rare - only a few per game, to be major "events"
Terminal only - one to end the game where fitting

Edit: the motivation for the poll is with a view to the design of PvP rules. If they are going to be common, I think the rules need to be good. If they are rare, we can wing it.
