It's all 50/50 for me. Good, clean graphics that can be married with a good, completely playable gameplay style that's not riddled with bugs but with superb graphics (Sonic 06 makes a great example of this, having excellent graphics but near-horrid gameplay) nor graphics that are super-hideous that makes it a eyesore trying to figure out what to avoid.
It's all about how well you make a game. So yeah.
