On to ideas. It seems you are searching for endgame projects, so I will share what I had in mind for my dream game. The goal was to ultimately build a launchpad, large rockets, and export exotic minerals to the homeworld (not unlike in the movie Pandora).
- Launchpads and launch infrastructure is enormous and can require incredible amounts of materials.
- Rockets can take a lot of research, and perhaps test launches are required.
- Rockets might require specialized composite materials that take a lot of research and specialized manufacturing equipment
- Rockets require enormous amounts of fuel.
- Sometimes rockets blow up and take infrastructure with them.

In addition to exporting exotic materials, another project could be to put more conventional materials into orbit to facilitate the construction of…. a space elevator! This would require a very large amount of materials to be blasted into orbit.. think arrays of launchpads and rocket factories. Also, a lot of ground infrastructure for building the “socket”. Once the elevator is built you can export materials much more cheaply.
Some other variations:
- Satellites to facilitate exploration, communication, mineral detection.
- Take the logistics chain to the next level: space transportation to other worlds. This might be good for a more isolated multiplayer game.
