No matter how much you run away from it, 'graphics' is one major aspect of any game. If it weren't for our greed/lust for better eye candy, we'd be stuck playing Doom even now. Or maybe Dave or something.
That being said, hacks that have good graphics generally appeal to a larger number of people. But because of the fact that the coming generations are getting better and better in terms of graphics, some people may just leave rom hacks, maybe. Idk. Then again, as merv said, these are two different things. So yeah, kinda confused now. XD;
