gamers are weird like that. I think you can still be successul without crazy graphics, but the PR you will get around the net will be dreadful because people want to justify their high end rigs or their next gen consoles. And those people are disproportionately more likely to comment.

But you also can't listen too much to the core gaming audience because they also don't think more subtly about what makes a game fun. And despite that PR good looking games can still sell. No wonder the market is so unstable, it's audience is fickle.
