And I'm not speaking about wacky post-apocalyptic superheroes. There are mainly four categories of creatures in the Fallout series: Humans, humanoid mutants, mutated animals and robots. Of these, robots are the rarest to encounter: they were manufactured before the war for the most part, so they are limited to ancient facilities and military bases and other such areas; they are the guardians of the Old World. Now, robots are product of advanced technology, so they shouldn't be too common, at least compared to other types of creatures. Still, they offer great utility both as combatants and workers and it seems unlikely that civilizations in the Wasteland, although struggling and rebuilding, wouldn't try to employ, adapt and maybe even improve them for their own purposes, especially as technologically advanced Nation-States emerge. In conclusion, in a future installment of the series I'd rather see modified robots and wasteland designs (rust bucket robot) than new, shoehorned prewar ones.
