Epicenter raised an interesting question - is WWIII necessary for Hard Space? I am still undecided on this. Will climate instability, pollution, and government insolvency achieve the three goals I've outlined above?
My apologies if coming in here is like beating my own dead horse, but I suggested climate instability, particularly climate change and pollution (a related factor, really) because nuclear wars are pretty destructive, yes but the damage is almost superficial in some ways.
Find some of these maps with estimated coastline changes circa 2100 under different estimations of climate impact - there's visible changes to Earth and will give players that feeling of "wow, this Earth is different, the coasts are gone, London is flooded, Russia is the breadbasket of the world?"
When you consider the majority of the population of this planet lives near the coasts and many of these populations will be displaced by rising sea levels but also squeezed by desertification as the arid "sub-tropical" climate bands on the Earth get wider and creep north (and south) making farming nearly impossible in many of these areas, you have a population shift that will affect many of the most populated countries in the world directly and almost all countries indirectly. I think you'd have events that will impoverish countries, redraw national boundaries, and generally cause the global instability you seek far more effectively than a nuclear war. The lack of farmland and so on might even spur the exploration of space.
