I'm the kind of guy that started out with the Black Isle games, but as much as I feel like Bethsoft really pissed on Fallout lore with the BoS and Enclave in DC and all that, I still really love the amount of love they put into the aesthetics and atmosphere. As ridiculous as stuff like Megaton and Little Lamplight were, there was just something about all the places from Rivet City to the ruined metro that had this oddly soothing spirit about it. It was enchanting, and really pulled me away from the disgust I had around certain other aspects of the game.
Overall, lots for me as a Fallout "veteran" to not like, but I still appreciate the work Bethsoft put into the game.
