Karibu,
Seems like the "Return to Hell" game will be the venue of some epic battles.
There should be plenty of chances to perfect the planetary attack. So far I have 17 ringworlds, all of them with several orbital shipyards building WP's and other defences.
With the max 10 ship targeting by planets it seems like there is need for a more combined defence (and attack). This is going to be interesting
