Yes TC Journey was Almost entirely graphics and music, and guess what? It sucked massive balls as a game.
The point of being a game is just that a GAME, and it;s gameplay, which journey is a miserable failure at best and barely worth 5 bucks let along the outrageous 15 for the (LITERALLY) hour long pile of glitter crap.
I admire it for it's art, and I enjoy the music, but as a gamer, it is a freaking disgrace of a bare bones walk in a straight line crap.
So no Graphics are not nearly as important as the gameplay which is one of the major factors you buy a "GAME" for.
Sadly one of the major gameplay elements of Ni no Kuni, it's combat, is a clumsy and terrible mess and really brings the game down.
Journey won Game of the Year.
So shall NNK.
I can stare at a knot in a piece of wood until it frightens me.
