RE: Gas giants
Rather than letting a gas giant be mined out, we should probably set "remote mining reduces value := false"
You could, of course, get much more out of a planet by colonizing, but remote mining might be viable for those planets out in no-man's land.
Note that the majority of huge gas giants should by Hydrogen/Helium, although the smaller giants can be others. (None of the races can colonize them anyways, so atmosphere types don't matter except for realism)
Also, due to the H/He composition of the gas giants, they should be started with a very low concentration of minerals & organics, but be great sources of rads (fusion reactor fuel

)
- Rock worlds should probably favour minerals over organics.
- "Ice"/Water worlds should favour organics.

Also FYI if someone clicks on the sector containing the star, it would show up like a normal star would (err, minus the actual picture) so you might want to force it to appear at 6,6 and describe it like event horizon or something.
A raised-bubble distortion of a starfield using an image editor would look really cool for the event horizon "star": star images getting smeared into arcs around the edge and all
