Draft of the rules and starting position:
To recap, this is a 40x40 map with toroidal wrap on noble difficulty. No barbs (nor any pre-placed barb stuff, don't worry), events or huts. Please realize that 40x40 is 1600 tiles, compared to the 900 that pbem25 has with a similar (but entirely land-based) map concept. So this is not going to be nearly as cramped.
The map is completely mirrored; i.e. there are 5 copies of every aspect of the geography, in the same layout as pbem25 (with players equidistant from one another). Here is what the start looks like:
You have
a pre-placed city with 5 culture; a scout; and a worker. Note the village at B, the railroad at D, and the Forest Preserve on the tile south of C.
Depending on your civilization's starting techs, certain things will be changed about your start:
Fishing: Your city loses its 5 starting culture.
The Wheel: The village on Tile B is removed.
Agriculture: The Corn is moved to Tile C (where it is forested and lacks freshwater).
Hunting: Tile A loses the forest.
Mysticism: Tile C becomes plains.
Mining: Tile D becomes flatland.
Additionally there are two civilizations with effects should you choose them:
If you are
India, you start without a worker.
If you are
Inca, you start without a scout.
Depending on your traits, you will additionally start with two free items (in your capital, in case that's not clear):
Aggressive: Library
Charismatic: +2 Population
Creative: Courthouse
Expansive: Hospital
Financial: 1 gold
Imperialistic: Grocer
Industrious: Castle
Organized: Supermarket
Philosophical: Airport
Protective: Granary
Spiritual: Warrior with the Sentry and Leadership promotions.
Clarifications:
a) Yes, Financial starts with a buck. Not 1gpt, not a gold resource. $1.
b) If your civ has a unique unit/building version of a starting unit/building of yours, you'll get your special version, not the regular version.
