Exactly. That's also the same reason why a game being too easy is the game's fault. One could object that players should be more disciplined and intentionally forego (e.g.) the stronger weapons in the game. But part of the fun of playing the game is to try to get the best possible weapon. Similarly, it is little fun to play e.g. tennis or chess against a weak opponent. Either it is too easy, or you don't give your best, neither of which is particularly fun.
