is it only one system? are there no empty systems connected to him that you could warp into?

if someone turtles off their empire (or reduces it to a couple of well defended warp points) you can often still get in through nebulae, black hole, or asteroid systems that are inside the turtle zone.

personally, i think long range warp openers screw up the tatics of the game. a good strategic game should have well defined front lines and rear areas and, although raiding should be possible, it should not be easy or decisive.
