[Suicide Junkie]

Abilities.txt is nothing more than a reference for modders.
It is never loaded by the game.

The first idea might be possible, though the space colony generator would be able to turn huge asteroid fields into teensy little space colonies.
I suppose if the player wants to waste all that valuable real estate, its thier choice.

I haven't had much luck with teensy planet types, though, so don't ask me for details.
