for some reason when other developers start creating a first-person perspective it always seems to turn into a FPS. they like to think they are creating an RPG but in reality it's nothing more than a shooter. take the witcher as an example. some would consider that a RPG but most that have played it would say it's really nothing more than a shooter with some flexibility on what skills your player has.

Do Deus Ex and Mount and Blade count?

Because RPG players like to see their characters pretty armor and throw their toys out of the pram if they cant. The majorty of TES players use first person but I can assure you there would be an uproar if third person was removed.
