If we can only get cities with so and so many members, could we also get fortresses? Castles, so forth, for every member we have, which would affect the FoI (not necessarily add to it. Just make it so that we can take from our pool of FoI an amount for FoI for every fortress).

This could be helpful for nations who do not want actual cities - I think Escobar's Desierto is one. But this way, you could also add FoI.

So, what do you say? Two fortresses per member? <_< >_>
