In the Great Britain variant each English province is a supply center and England starts with six armies. Thus, England is the “strongest” country, but can’t do anything until another player agrees to convoy one of his armies (or he is forced to disband one of his units and then builds a fleet after retaking the supply center).
The victory conditions are 19 centers.
