Oh, it's first person and third person. The last two (7 and 8) are the only ones with a first person view, the rest of them are all third person view (the classic ones fixed camera in each room, the modern ones are viewed from your shoulder).
But this is for the main games only, there are some spinoff that are FPS: The Resident Evil Survivor series and the Umbrella/Darkside Chronicles I think it's on-rail shooters, like those arcade games, so it doesn't feel that much like a real videogame, but there is one game, Resident Evil Dead Aim, that are a full game in that style, so maybe you should check it out!
