I was wondering if the game could include a perk / skill for Extra Sensory Perception? During the cold war, USA, Russia as well as England has some experiments concerning this. This can open up a whole new field for exploration. i.e. psychokinesis, telephathy, clairvoence or remote viewing etc... There are some discussions also about humans developing these attributes eventually as a natural path of evolution, thus a nuclear fallout could jump start this. Fallout already have ghost and zombies in various instances, why not expand on it and include werewolfs, vampires etc... it will appeal to a whole new audience
The discussion on item identification is also interesting which is sort of like the "lore" attribute on other RPG games. But different items may require different types of "lore" i.e. electronics components require high "computer" skill to identify, unique swords / melee weapons require high "melee" skill to identify and so on...
