As far as fictional societies to live in goes it's hard to beat an optimistic sci fi setting lmao.
Although I might choose the Ascian civilization from FF14, as long as it's before the Final Days. Eternal life and post scarcity powered by magic, and the way most people self actualize is by literally creating life like gods. If it's early enough I would travel to other planets myself and possibly avert the apocalypse altogether.
But if you're living on a planet far from the fighting, sure there might be a slight change in your day-to-day, but you wouldn't be consumed by it. Even living in the Alpha Centauri system would be far from the fighting but close enough in to be a core world in the Federation.
well, technically, FC assimilated Earth happened in an alternate timeline, but you make a good point about the Domino War and wanting to avoid that. So, yeah, Iโd want to arrive after that ended.
