I prefer the idea of VP limit as that is easier to track than days passed on the server. Before you know it 125 days have passed.
Maybe the kingdom needs to hold the lead for a couple days. Gives others that last minute chance to smash some hammers on them haha XD
I would actually like it if it lasted longer.
Maybe there should be a limit on number of treasuries you can build. But you can capture as many as you like
So now it becomes territorial. VP generation is based on how many fields you own too, treasures become a smaller part.
You are changing too much at once to accurately test the effects of each change being made. You wouldnt be able to attribute a better or worse gameplay experience to a few features if you change so many as you are suggesting.
They shortened server length in kingdoms because in legends they last many months and this was boring and annoying for people.
You cant just do a VP limit, you would also need a day limit because on smaller servers it would take a long time to reach some uniform VP limit because VP numbers are higher when there are more players due to robber hideout mechanics.
