True, you can see the other players' civic choices once the game starts. It's possible that what you pick publicly may convince others to follow your superior strategy. Or, they may see your choices after the game starts and waste several turns in anarchy to copy your strategy...
I gave you guys a pretty nice capital to speed up the game a bit, else builds and research would take forever. So, your capital includes:
17 pops
20K culture
200 gold
Holy City of your religion
Palace (duh!)
Walls
Barracks
Stable
Granary
Aquaduct
Lighthouse
Harbor
Forge
Library
University
Observatory
Colosseum
Market
Grocer
Bank
Courthouse
All four buildings for your religion including the shrine.
All six of the other religion temples (I had to do this to raise the happy cap to support 17 pops).
Each capital, runing zero specialists, generates about +10F @ 17 pops, 14 base hammers, 60 base commerce. You have access to about 4 happiness resources, 7 health resources and all strategic resources. Every leader has different happy and health resources to allow working together via resource trades if that's the way you want to play it.
I had to give 3 or 4 leaders Hit Movies in their capital to allow +17

. I didn't have to do that to all leaders because some happy resources provide +2

while others don't. I did my best to make things as fair as possible.
I was thinking about sending everyone a screen shot of his capital and island prior to starting so that they could formulate a strategy. It's possible that seeing these screenshots could alter GP choices and/or Civic choices.
BTW, I will give everyone map knowledge of everyone else's island, but the rest of the world will remain unexplored. There may be surprises hidden in the fog...
EDIT: Each of you start with one city, one settler and two workers as agreed previously.
