Have the game set up in a few days (working on the map), but here are some more details.
Each player gets a nice cluster of 20 home systems. Only 2 warppoints lead out (they are separated by 2 systems, so you need 2 fleets to guard them). Both WP’s leads to a system that is empty expect for 1 Ringworld (only 150 % Ed

) which will be of your preferred Planettype/Atmosphere. From this system, 5-6 warppoints (to many to guard) leads to a central cluster where the goodies are located. This should lead to some interesting strategical decisions. Hide in your home cluster and try to defend your Ringworld or go for the goodies at the centre which will be hard to defend ? And on the attack, go for the Ringworlds or bypass it and go for a rampage inside the home clusters ?
