Been thinking about multi-race starts, on one planet, and what it always results in.
Given a nuclear war, it will now pretty much always end in the extinction of one side.
Given that there's a lot of media coverage of any kind, be it books, essays, films, games, that depict survival in such an environment, be it by means of bunkers or old subway tubes, shouldn't that be possible in Aurora as well?
I think this could be eased by having a "population-dependent infrastructure", that is only slowly destroyed by orbital attacks (10%, for example), not seen on sensors, and will allow survival of a small amount of populace, maybe without pop growth.
This could work together with a base production that automatically constructs conventional industry if there is significant unemployment.
Suggested figures:
PD Infrastructure Min would be 10% of the required infrastructure at colony cost 1.5
PD Infrastructure Max would be 10% of the required infrastructure at colony cost 2
Complicated:
IF (10%+ unemployed) OR (Construction < )
Generate (100+SQRT(Pop in millions*10))*MP Construction.
IF (PD Infrastructure < PDI Min, produce PDI), ELSE (Produce Conventional Industry)
Simplified:
Every Million of unemployed Population counts as ONE Conventional Industry, modified by Colony Cost. Capped at 10% of total populace.
Will automatically produce PD Infrastructure if below PDI Max.
This means that uninhabitable worlds have a lower base production, and thus produce Infrastructure significantly slower. It also means that a populace devastated by a nuclear strike can, albeit slowly, recover.
The system doesn't really help building fresh colonies, unless on perfectly habitable worlds.
