I made this scenarion from a map that I made called "4 islands and a Bay". Go here for a mini map of it.

In this scenario most civilizations have 3 or 4 cities, The English Russians and Japanese all have their own islands. The Americans are on a small archipelago. The Babylonians, Greeks, Romans, and Zulus are on one large continent.

So how is it accelarated?
It sounds to me as though it could just be an ordinary random game

well, one would assume that several cities, units, techs etc are already built/discovered.

yes but isn't that the same in every other scenario?

This is a great idea!

The point is that it's a normal game, but you are already several turns in. This is for people who don't like those early turns with just a city and a couple of units. Right?

This was a great idea. I've made a couple of these myself but they were all Mods.
