Alright, here are a few suggestions for details:
Emperor
large map
12 civs
(not sure on map settings)
There would be three victory categories:
No Holds Barred: Earliest non-diplomatic victory.
Culture: Earliest culture win. Special rules would be not allowing more then X number of cities conquered/razed by you. Not sure exactly on how many cities, but you shouldn't be able to just destroy everyone else to ensure your cultures dominance.
Earliest Space Race.
I figure time is a better yardstick then score, and the non-military victories would add variety to the game style - otherwise everyone would just use the 'Diety Win' strat, and that gets boring.
If theres interest, I'd be willing to handle the logistics.
Better if we could get site sponsorship -hint hint-
