Stoned huskythoughts. (CW: thinking about video games that would be cool if they existed)
A single player 3X game that zoomed from Cities Skylines to Stellaris. Explore the resources, build trade networks to support the cities that you build on your colonies.
Get to see the anomalies that you find in the galaxy actually effect your citizens.
Have cities that will effect your space empire be more than just stats. If you wanna run your empire, actually run it.
Also, there will be no way to win through aggressive actions. Negotiate fair deals with your fellow galactic citizens and watch civilization prosper.
Oh, and also, no Corporations, only buisnesses that are owned wholly and equally by the employees.
The task is to efficiently lay out your cities to take advantage of the resources on-world, and all the resources off-word too.
