Graphics can help a game, but if the game sucks to play, it's still a bad game no matter how amazing it looks.
FFXV looks amazing now, and we can kinda create some idea of what it's gonna play like in our head, but if it turns out really boring to play that will be a big bummer. When it was Versus XIII the one gameplay video they showed looked like a mature PS3 Kingdom Hearts game, which I would have been more than happy to play. Now it looks more like a FF Type 0 game. Having never got around to playing that PSP fan translation, I'm excited to try FF Type 0 HD to somewhat percolate an idea of how FFXV may play like since they are from the Hajime Tabata.
