When I was old enough to care whether I won or lost at games, but still too young to be any good at them, I decided RPGs were better than action games. After all, I could play Contra for hours and still be terrible at it - while if I played Dragon Warrior III for the same amount of time, my characters would gain levels and be much more capable of standing up to whatever threats they encountered. To progress in an action game, the player has to improve, which is by no means guaranteed - but to progress in an RPG, the characters have to improve, which is inevitable.
