So you're saying every game is a RPG when you play a character...ok. That's not what determines a RPG but who am I to say. FF is a RPG because you play different Characters with different roles. Zelda is NOT a RPG, it's an Action Adventure just like Metroid but with a different point of view. Portal is NOT a FPS. It's a First Person Puzzlegame. Doom is a FPS, Halo is a FPS, Destiny is a FPS with crossover elements. Deus Ex is a FPSRPG for example.
