Storytelling plays a significant role here too. Narratives are pulled from the Bethesda-made games and their expansions, including Fallout 4. If you're looking for a different way to deal with a super mutant encampment or a rad roach infestation and Fallout Shelter isn't cutting it for you anymore, maybe this will when it's released in a few months. Need a video-game board-game fix before then? There's always Dark Souls.
