Yeah, I love using "It's like the buggers!" when describing this game to people, especially since I know that was partially your intent.
But about wormhole guardposts:
1) Does each one in a system raise the ship cap for that system?
2) Does each one in a system raise the number of spawned ships during a reinforcement to that system?
i.e., if I take out all the wormhole guardposts on said AI homeworld, am I just shooting myself in the foot, or would it trim the numbers some...
