The whole team shores up the borders and goes pure boom on the assumption that the other team will be aggressive and fall behind in a tech race. Early fishing is very important but because the oceans will not be militarily contested, other than by a token gesture, fishing boats should be deployed in obscure parts of the map. Loss of fishing is ultimately inevitable so a steady farm replacement program should be in place by age 4 in conjunction with granary upgrades. Caravan routes should be established as soon as possible.
The boom should be supplemented by a concerted effort to construct economic wonders.
Each player is responsible for securing defences while concentrating on an economic boom.
East Meets West map.
This is a low risk strategy that can only suffer by an aggressive early boat sweep. Most likely it is countered with an opposing team turtle.
Risk: Low
Effectiveness: Medium
