A game of Advanced Civilization is rarely satisfying without the full compliment of players, and yet, getting 7 people together for an all-day game is usually difficult. For this reason I came up with a variant map based on Ancient Greece and Asia Minor for 4 players. The map is somewhat "tight" and players will have to compete for city centres and farming hinterlands.
The Map(Click on the map to see a larger version.)
You will note that ships are very important in this map, and there are no landlocked nations that are safe from seaborne invasion. Also, city sites are at a premium, with only 28 on the board, or 7 per player. Farmland is likewise strongly limited, and Agriculture is important for everyone. Competition, especially in the early game will be fierce.
I have played this board and have found it to work pretty well, and we finished an entire game in only 8½ hours. Feel free to print copies of the map for your own personal use; simply ensure that I am still credited as the designer and that they are not sold for cash without first recieving written permission from me.
