I would agree with your first point.

The game is already full enough with stuff to do that takes potentially ages for the modest player to achieve, even if it was functioning correctly, without the need for adding yet more content.

That being said,any ideas will be greatly received,as part of the idea of the forum, is too see how the game is viewed, and how many ideas they can come up with for free from a wide base of players rather than a few  paid for employees .

No I have no idea what Kings of Babylon is about.

 Potential gripe 

First:

Its a borrowed idea, and its possible they are already aware of it.

Second:

 It may be a copyrighted idea

Third:

The name Emissary,emissary suggests something benign, rather than malign.

Fourth:

The  first restrictions suggested, means potentially there will be few towns available. 

The later restrictions and your implied loopholes which I fail to understand. 

Fifth :

The idea of extra bases of operation, legal or otherwise is not new and should go down well with those eager to sell and those prepared to buy.

They would certainly relish the idea of moving resources around for free.

Sixth:

I think few,again is the operative word,I fail to see how this would eliminate the need for alts , there's little real need for them in the first place,its just a perceived need,and  the idea of alts isn't new either.  

If everyone was allowed one alt , no one would be better off than a one town limit, and just like the first person playing this type of game who thought 

" wouldn't it be smart of me if I built a second unit? I could enhance my game twice as fast as everyone else because no one else will have thought of my idea",

Then players would think. I am allowed two, no one will notice, object or copy if I have three. and so on as now.

Seventh:

Would this really get rid of messy data?

Some good points, thanks for the reply!

Dont think its copywritten, that other game has been dead for some years now doesnt exist no more.
