I am not sure how a ringworld could be a very effective defense considering the time it takes to build it. It certainly couldn't be built on the front line of a war. I would use cloak or suicide ships to keep checking your systems for ringworld construction then wait till right before it was done and waste all those bases with no defenses on them and or all the shipyard ships or take out the ringworld before you could put defenses up on it. Also perhaps capturing the world myself after you spent all the resources building it. I am also not sure how the points are calculated exactly but I doubt the sphereworld would be worth more points than the number of ships you could build with the same amount of resources. Unless of course you had the ship limit to worry about. But if you had 2000 ships I doubt you would worry about it too much.<G>
