This list focuses on official, developer-backed multiplayer modes. What they share in common is a particular game loop, with resource gathering and crafting complementary to other goals - from exploration and fighting to growing a city to managing a successful amusement park or farm. This list broadly covers base-building, automation, survival, and certain types of crafting games. So we’ve created a list of some of our favorites that support cooperative play mostly online multiplayer with a few entries that support couch co-op. But these games are often more fun with others, letting you create abominations together or ruthlessly mess with each other’s work. There’s that perfect gameplay loop that comes from doing menial tasks and then, later, building systems to help automate those chores. Base-building and management simulator games scratch a particular itch.
