> No one can say that Zelda is an FPS.
Congrats, you've found the meaning.
RPG: Role Playing Game
FPS: First Person Shooter
You see now that Zelda is technically neither of these. The definition of both more easily fits the Grand Theft Auto series. To be a grammarian douchebag, very few electronic games fit the mold, considering how the player plays it is more important than the content in defining an RPG.
Adventure is a word that fits perfectly the scope of Zelda Games.
