Factorio has rolled out of the factory and is now officially out of Early Access on GOG.com and Steam. This is a simulation for Windows, macOS, and Linux where you build and maintain your own factories. This carries no release discount, as they reiterate their hard line on such things: "Discount Disclaimer: We don't have any plans to take part in a sale or to reduce the price for the foreseeable future." The Launch Trailer discusses the game's lengthy production cycle and shows off gameplay. This post on Steam discusses the release and what's changed in the full version. Here's the official description:

Factorio is a game in which you build and maintain factories. You will be mining resources, researching technologies, building infrastructure, automating production and fighting enemies. In the beginning you will find yourself chopping trees, mining ores and crafting mechanical arms and transport belts by hand, but in short time you can become an industrial powerhouse, with huge solar fields, oil refining and cracking, manufacture and deployment of construction and logistic robots, all for your resource needs. However this heavy exploitation of the planet's resources does not sit nicely with the locals, so you will have to be prepared to defend yourself and your machine empire.

Join forces with other players in cooperative Multiplayer, create huge factories, collaborate and delegate tasks between you and your friends. Add mods to increase your enjoyment, from small tweak and helper mods to complete game overhauls, Factorio's ground-up Modding support has allowed content creators from around the world to design interesting and innovative features. While the core gameplay is in the form of the freeplay scenario, there are a range of interesting challenges in the form of Scenarios. If you don't find any maps or scenarios you enjoy, you can create your own with the in-game Map Editor, place down entities, enemies, and terrain in any way you like, and even add your own custom script to make for interesting gameplay.
