You can choose first person or third person on the fly in TES. I would call them FPAARP (First Person Action Adventure Role Playing) games. TES is Fantasy and Fallout is kind of science fictiony post apocalypse. I don't really know too much about them seeing as I really played one (bought TESIV in highschool and quit my job soon after). As far as comparison to games that aren't RPGs, TES is a really detailed medievil GTA. xD Hope I helped.
Also, best PS3 RPGs= Disgaea 3-4!! <3 and also TES IV.
