There is a single player option but the game is way more interesting as a multiplayer game.
You have 30 days to avoid a meteorite destroying your world. You start on a wild planet and you need to progress through several technological advancement to build a laser able to destroy the asteroid.
You have some classical resource collection and processing. However where it become interesting is the fact that every action impact the environment, slowly first then more drastically towards the end.
If the miner left his tailing on the ground untreated then it will slowly pollute the ground and impact the production of the farmer.
If one of the woodcutter cut too much woods in the forest then you create some deforestation, less trees means less pollutions to be absorbed. The hunter can hunt some animals species to extinction or help them to thrive.
Since it’s a multiplayer game there is the possibility of voting laws to protect some lands and which money will be used for global exchange.
It’s a fascinating game, unfortunately it is quite time consuming and not very polished but I love the concept.
