Well I just came back from Moh Ki to Vadda the other night, took me 15 minutes. The original trip took me 3 evenings ... So its a pretty brilliant design to have a small world which is hard to find you way around in; basically it feels like a large world but you constantly encounter other people on your travels which makes it feel more populaated than it is.
I am still hanging the noobie cities because I decided to start a character all over again (drrr) so that's probably why I don't see more than half a dozen people at any one time.
Also, it doesn't get nearly as dark at night! I have mixed feelings about this.
