I don't think nix is a graphics whore.
I think he just holds them in a higher light than the majority of gamers. I understand how the older games would look/play like crap compared to some of today's games.
Although I do prefer the story/plot of FF6/4 over the plot of 7, but I still like 7 a lot.
People have different tastes and you can't really force someone to just suddenly side with our belief of "story/plot/gameplay is more important".
Nothing is wrong with nix's views. While I do not agree with them, I'm not going to give him flack for them, because it is wrong to do such a thing.
I don't see why drama has to be created just because someone has differing views.
