@Ostaff That's great, I think cities like the one I mentioned will become easier to exists!
There are enough plots for more than just a house-per-guild
Guilds cities will be more targettable for sieges then before, because of (potentially) smaller number of people joining them, making them less defendable.
That makes neutral cities a good place where people would stock up their resources, and protect them together each other...
The risk a guild would outnumber the others taking control is less feasable due to the interests of the many to prevent it happening.
Free-for-all crafting stations will give less importance to direct citizenship itself.
I think even big guilds will partecipate, if this city would be built in a middle-area, isn't it?
And if you play a good co-ownership of plots, you can actually live in more then one city (both neutral alliance and guild personal cities).
Resources will be still a problem to manage to, but they can be "politically" partitioned between city's exponents.
