I looked at the map and the demo to compute the pop of the other teams.
Maverick has 7 cities, we see 2 (with pop 2; 1) and from demo 57,000 people, so they 've:
3, 3, 2, 2, 1, 1, 1
Amazon we know all cities (best from my point of view), so they 've:
8, 6, 4, 4, 3, 2
CDZ has 6 cities, we see 5 (only the Barb not) they 've:
8, 4, 4, 3, 1 and bacon
Quadronia has 7, we see also 5, they 've:
8, 5, 5, 4, 1 and Cygnus and Singularity.
The 3 cities from both has pop 2, 2, 1. I would vote bacon 2.
Then is Merlot
They have 6 Cities and we see nothing, from F9 we know the capital Merlot Castle has pop 11 and from demo they 've 1236,000 people, but I 've problems to solve the problem, I get allways 1,000 people too much. pop 11 is 1051,000 , iE with 5, 4, 3, 3, 2 or 4, 4, 4, 3, 3 ...
perhaps somebody can solve it (help my computing)
