I myself really enjoyed game called "Mindustry". Its a mix of factorio and tower defense game of sort. You basically construct small factories to expand your defenses and produce ammo for your turrets. Compared to factorio production chains are much more simple and game is more focused on tower defense part but it all really fits nicely together. And its certainly worth mentioning that unlike most other games mentioned here its a proper modern game with nice looking interface and proper graphics instead of asci tiles. I absolutely recommend checking it out!
