Saying minecraft has bad graphics is like telling Picasso he had anatomy wrong. Its 8-bit graphics, and it looks good for what it is.
I don't know if I agree with what you said, but;
Saying Minecraft has bad graphics is like saying Crysis has great graphics.
You are pointing out something obvious, that absolutely no one on the planet cares at all about.
"Hey we made you this game, you can't do anything in it at all, but it has the best graphics of any game ever made"
I'm sure the people [censored]ing about Minecraft's graphics would buy it.
My point is, if you think of Minecraft, and the first thought that comes to your mind is graphics, then you aren't a gamer.
