Giant Stars?

[dogscoff]

D, A spherewolrd isn't worth all the mucking about?

Not in a system like that, no. If I'm gonna build a sphereworld, I'm gonna build it somewhere useful.

Apart from the well-known fact that you only ever build a sphereworld for the hell of it anyway, why would you place it in some dead-end system with no planets? By the time you've got the necessary stellar manipulation for all this arsing around you've probably cut the useless empty system out of your warp-point network anyway.

I think an option to shift asteroids about in some horrendously out-sized ship would be a good idea. The project should be even more of a folly than building SWs / RWs, but do-able.
