I like to believe that the Steam Deck was never meant to be sold as a product.
It was just Gabe who wanted to play games on the deck of his yatch, so he got few engineers at Valve to work on a solution.
Of course the engineers were a bit too enthusiastic and turned it into an actual consumer product.
Welcome to Facto-RayO, a 3D game engine built in Factorio
The price of electricity produced is an interesting metric to look at but can be very misguiding alone without more data around it.
It like comparing the price of rain water compared to well water.
The same way that solar is cheaper than nuclear, rain water is much cheaper than well water, you just need a roof with a gutter to get rain water.
Does it means that we should stop using wells and rely only on rain water and use water only when it rains ? Or do we also want to have tanks, do we need a backup for when the tanks are empty ? …
Eco could fit your description.
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.
It’s not a new Fallout game, it’s a mod from independent developers so you can except a higher standard.
