Slipways is a great turn-based scifi empire builder that focuses on colonizing planets and building trade routes (titular slipways) between them to synergize. It has chill soundtrack, pretty visuals, and no war to stress about, your only worry is optimizing your empire layout
Ooh, thats sounds right up my alley. Used to love civilization and stellaris and those types of games, but war was always my least favorite part of the gameplay. It gets in the way of my perfect empire.
