It's not a unique ability (you can do it in Minecraft and a few other games), but it's a bonus. Someone created a ray-tracing program in-game, to run a vaguely Doom-like game ^^
I got Factorio yesterday and have started to familiarize myself with what is, essentially, a signar-driven conveyor belt simulator.
Story is charming, although unrealistic; you lose your spaceship on impact, are the sole survivor, and will go on to build a massive and high-tech base, because you have an IQ of 400.
Any of you have played it? 8-)
