You start factorio and manually dig up some resources. Then you can build a mining drill to automate the mining. At which point you'll want to build some grabby arms and boxes to store your new resources automatically. But then you'll realize you can make conveyor belts and transport these to automate the production of goods.
This loop of manually creating something new followed by figuring out how to automate it is the core to the game and it's super fun.
If you're the kind of person who likes crafting games, puzzle games, or automation games there's probably something here for you.
I feel like I didn't do a great job of describing it, so check out the video embedded below.
