As Nerd3 described it, it is a game for people who got bored of Minecraft (
youtube.com/watch?...). In Factorio you can automate almost everything. Sure, you need iron to build a thing, but who wants to go mining every time? Drop a miner on that iron ore, deposit the ore on a belt, bring it over to my furnace, smelt it into plates, belt the plates over to an assembler, use the iron plate. Throw in a little bit of Don't Starve in the form of a technological tree you have to go through resourcing new things. Sprinkle some aliens around that will attack if your factory pollutes the area. Now you have Factorio.
