On a random note
Can we have some sort of in-game mechanic that will prevent future Peacekeeper Incidents from reaching one-sided planetary war?
Like, for example, if General Planetary War happens, a side can release or threaten to release TN neurotoxins that wreck the earth entirely. This would be abstracted by radiation levels being set to something like 10000, simulating both sides going all-out with biological warfare. One side would get an advantage, in the sense that they would have more surviving equipment to take off planet, but both sides would be objectively worse off and less secure because of extrasolar threats.
It will still let war be possible in the far future (when a full space race is done and people have powerful extraterrestrial colonies) while restraining near term actions. It also will allow people to be more aggressive, because they know it will be within the rules.
