I voted "as long as the other races were good," but I have to expound on that.
Show me a world that looks just like medieval Europe, except that the humans are replaced by seal men, and I'm walking away. If the world doesn't have humans or the humanoids we know, then I fully expect the writer/DM/whatever to have put some serious thought into changing the culture along with it.
Now, I'm not unreasonable. We're all humans, and that means we all think like humans. Any campaign setting we come up with is going to have some resemblance to human culture, religion, and anthropological/societal development, because that's how we think. So I don't expect drastically different cultures.
But I expect some pretty hefty alterations. Orcs, lizardmen, or ferretfolk are not going to think like humans. They're not going to have developed their societies in the same circumstances as humans. And dang it, if I'm to play in a world where those are viable races, I absolutely expect that their societies are going to look very different than anything we've seen in more traditional D&D/fantasy.
(And if it sounds like I've given some thought to this, I have. Someday, I hope to be able to make use of said thoughts in a printed product, but I'm very much not holding my breath.)
