you be talking big for a player who only survives on internal takes. the biggest city you took was what? 2 or 3K from a player without an alliance? if any cities do turtle then you will be no danger dude. Never cared for the expression "turtle up" - usually used by players who get frustrated because they are incapable of taking a city that is well defended....
I do like to turtle myself on a red island and watch the BP roll in.
Ya ya ya heard that one before. If I was some simmer that never attacked you could pull that argument. Try again.
