A darker, nastier Wasteland, maybe? Heck, if it's possible to make a total conversion in which there are no other living people, just the ghouls and the beasties, I'd love to take that for a spin. I'd rather create a curated experience using mods, adding only things that are either too brilliant to ignore or that are at least thematically appropriate. Yeah, that guy is dressed as Doink the Clown and over there you might see a whack-a-mole hammer attached to a suit of power armour. The danger of easy-to-install mods, for me, is that I tend to throw so much crap into my game that there's no consistency. Imagine that! Turns out we're all on the same internet after all. The important thing to note from that video is that your precious mods, created on your PC, might sneak through Bethesda's internet-tubes and find their way onto consoles. Once you've opted in, you'll be able to browse and install mods from within the game. The modding tools have now moved into open beta and you'll need to follow some simple instructions to get them working via Steam.
The Creation Kit - which Bethesda say is 'the same tool that we used to create Fallout 4' - is now available to download via the launcher. Fallout 4 just got a lot more interesting.
