Mid & late game crises

[Saros]

Probably more of an expansion or DLC idea but have you considered events to break up the mid or define the late game. Midgame could be raider/slaver clans banding together into a powerful horde, a long lost galactic republic military ai reawakening and going full skynet and late game could be millions of arachnids awakening across the whole planet, aliens invading or a galactic republic troopship whose inhabitants have been in cryo-sleep showing up over the planet.

Events like these could be a cool addition and diversify the late game mega-wars which can be a bit of a slog.
