X4: Foundations. Just started a new playthrough with the Kingdom End DLC.

Its the closest to Eve online, except being offline, singleplayer, pausable and moddable. It supports many playstyles and can also be played semi afk, which i like. At times it can be incredibly frustrating because the UI is complex and the AI of your fleet members can be very stupid.

Still i enjoy just doing my thing, playing for a bit, save and conrinue later. Not a lot of games support this. Others that do for me are Factorio/DSP and Drox Operative 2
