Oh my bad. It was the new colony crisis events added this year.
Anyway, there is a lot of endgame space to improve on (pun intended).
1) Implement proper map painting / faction warfare /diplomacy.
- Proper assaults and takeovers on planets instead of just bombing them to resettle.
- Claims on sectors recognized between factions. Player faction recognized (settled entire system, game still doesn't feel like I have a claim on it, lol)
- Diplomacy between factions, more interactions with faction leaders, pacts of non-aggro, defensive, military alliances etc.
2) Implement endgame crises Stellaris-style.
- Global Remnant awakening. Interaction with the Remnants, farming rep, rewards, goals, etc.
- Return of the Domain. No brainer, all core gates activate and advanced Domain forces pouring in to reclaim the savages. Cannot use gates until crisis resolved.
- Return of Ludd. Escaped from Domain sentence during gate hack, spent eons in cryosleep, now back in action. Luddic church and path are ecstatic and unite in global crusade against infidels carelessly slapping AI cores in their colonies, namely you.
- Doritos invasion. Instead of useless Hypershunts they are actually high energy gates where Doritos start pouring in. Potential Remnant ally against all organic life.
3) Mentioned before, rework useless and random Tech Mining casino into actual tech recovery, study, and engineering facility with 3 upgrade levels.
- Research advanced weapons and ship hulls based on Ziggurat, Remnant, Dorito, and Domain tech, etc.
- Build gate ships to spam more gates, gates should have serious upkeep costs though
I can go on for hours, but you get the idea.
Stellaris and Endless Space are deflated balloons, and their teams struggle to implement anything fresh besides few text popups or a reskin, while this game has immense potential and I enjoy it a lot

But devs do need to pick a side - come out of the closet and join Steam or GOG (which is more in touch with the indie nature of the game), or both, its a serious market share since there are almost no good space games around, and good influx of cash for devs to keep doing what they love.
