We control all but 1 island in 44 lol
Thats not a good thing lol - however if you did it right it could be.
You will have no targets early on so competition for city's in your alliance will be massive, good players will get bored - want a fight, blood lust is a interesting thing in the game.
But as i said however, if you proceed across the oceans as a stronghold - taking city's on the ocean boarders and stacking them until ready to proceed further, then you will do very well.
If your guys start heading for the rim because of lack of targets, then you can say goodbye to Battle points and city's.
Advantages and disadvantages to everything, you must just balance it.
