Ive thought about it a bit, and maybe dead asteroids should not be colonizable.
The reason I say this is the game is kind of lacking in dead areas, which i think is particularly harmful to concepts like piracy and raiding. Also, almost all battles seem to be sieges. Dead asteroids are already in the game and adhere to this idea... sort of. You can't put logistics structures there and they have no mines. But they are virtually always built up with heavy defenses... requiring a siege, and making raiding impractical, and making empires walls of steel with no vulnerable points.
Also, dead space would serve to make systems feel less crowded with things you gotta colonize.
Unfortunately I couldn't find anything that leaped at me and said "Mod Me!" for this so oh well.
The primary practical concern is that it might cause the AI to crap out... I doubt it wants to deal with dead areas.
In the meantime im going to try lowering their tactical points.
