Fallout 4's crafting system explained by Bethesda's Pete Hines

That might sound complex but Fallout 4 is skipping the need to learn anything too out there by following a more WYSIWYG approach (What You See Is What You Get). "You don’t need to know scripting. A lot of it is really visual programming," reassures Pete. "You saw in [the] presentation, [they] put down a generator and you hung a light bulb in your house". In-game systems like that work just like they would in real life. If you need to run something you need a pylon and wire to connect it to a power source. If you don't have any wire you need copper to make some, and so on. "It’s common sense visual stuff," continues Pete. "If it doesn’t connect to the generator, the power doesn’t work. We’re not faking it".
