I feel like they really looked at some of the most popular mods for ideas to put into this game, like more houses (or in this case, creating them!) and put them in this game.
My hope is that it isn't just in one spot out in the Wasteland somewhere and that you can actually do this in a bunch of places, if not everywhere. At the least, in major cities where you can buy and own plots of land.
The only thing I feel will be necessary to be modded in are auto-sorters and displays. I want a gun wall, a money wall, a gold bar shelf, medical cabinets, etc. Mods be praised!
