if the population can be count on ships it will be very good for suicide junkie's Pirates&Nomades i think
imagine that we can take advantage of th population even if we play a nomad or pirate?
for the ring/sphereworlds i think that the only thing very annoyning is that you must move some SYships to the star and build a big number of bases to be able to make your world...the idea of making a shipbase with 2040 KT and only 1 movement point is quite good i think...
