I have heard some random information about SSP, but can't confirm anything.
Basically, don't worry about off-world colonies, they have declared independence from whatever bad organization they were in. Now they are recovering.
The situation I've heard is far more different than CG 's version. There are real space colony & colonists, like you would expect in any sci-fi settings. People were not treated like slaves in other part of SSP.
Also heard about very very weird time-flow in space.
And a space Disneyland somewhere.
