The Most Addictive Games Similar to Oxygen Not Included

Colony management simulation games are fun in that they allow us to test our management skills in a relatively safe environment, where we don’t risk being dethroned, deprived of power, or even killed by angry peasants or other townsfolk. We also don’t risk other people’s lives, so we can safely try our hand at building a self-sustaining colony on the surface of Mars, or managing a safe shelter for the survivors of a nuclear explosion.

While it all may sound a bit silly, that’s what makes games great in general – they allow us to experience otherwise unrealistic or even plain fantastic scenarios and events in a consequence-free way.

Management simulations often come with open-ended gameplay, where you are the one who sets goals and objectives. Such games usually have only one requirement – make sure that your people, or gnomes, or dwarves, or other living beings, survive and live their happy lives. But the way of achieving that is most often entirely up to you. You have to carefully manage resources and deal with a variety of challenges, such as dangerous environments, deadly enemies, or even your people’s basic needs, such as hunger and thirst. Only when you learn all of the game’s mechanics in and out, you will be able to use them to gain the upper hand, allowing you to make a thriving and self-sustaining settlement.
