Oxygen Not Included is like the customization and detail of Sim City mixed with the jobs and resources of Fallout Shelter, with it's own big twist. You start in the middle of an asteroid and have to work your way up both the technological evolution chain and the actual asteroid itself. You start with barebones tech and have to research yourself all the way to space travel. You are able to automate certain tasks in the midgame, and are able to travel the final frontier itself in the endgame. Even though there are a few bugs when fishing, and you'll have to hit the reroll button in the vanilla game a bunch of times to get the ideal dupe for a job, it's by far worth the price. Oh, and did I mention there are hats?
