Fallout....Fallout never changes.
....so, uh, I guess it totally does. When it's made in Minecraft, that is.
Yes, the Minecraft modding community - with their infinite amounts of both creativity AND time - is hard at work recreating the Capital Wasteland in Minecraft, complete with the UI, the brahmin, and everything else a Vault Dweller could possibly want.
It's called Project Wasteland, and is still in development, so no downloads yet - but, knowing Minecraft modders, this will be finished eventually, and we will not ever be able to fully appreciate the time that went into this.
As long as a Creeper blows up Megaton, we're totally cool with this.
