Factorio is a 2D game about building factories on an alien planet. You will be mining resources, researching technologies, building infrastructure, automating production and fighting alien enemies. The core mechanic being that users need to find resources in order to create factory parts in order to create even more complex machines.
Pro Cooperative or PvP building
Factorio also supports multiplayer, allowing many players to cooperate and assist each other, or work against each other in PvP. By default, multiplayer games run the CO-OP freeplay scenario where all players work together to launch a rocket with a satellite into space.
Con Can become rather repetitive
There's really little payoff for being able to build really long chains of automation, it usually results in being able to open a new tech tree which allows the player to continue the process of building automation chains ad infinitum, which, admittedly can become rather boring after a while.
