Delurking to post about my experience on VFK so far.
For the first two days I never once saw anyone or was able to chat.
Today I am (mostly) able to chat and I see other people -- but not necessarily all of them! I was in a room with mileycyrus for a while, and though I clicked on all the visible characters, none of them seemed to have her name.
In one room (blacksmith room of the Old West) I could see chat but could not see any people. I could not chat there myself.
In some rooms I can't chat; don't know why.
My character's feet are getting tired.

It would be nice to sit.
Bugs and other issues I am noticing:
The dictionary doesn't seem to allow you to type a person's name unless it's already a normal dictionary word. This can make it difficult to address someone in a crowded room.
People can easily block gates and doors and make it impossible to leave a room. (Also -- I hope they add markings to show where the exits are, soon.)
For some reason VFK is noticeably laggier on my Intel Mac FireFox than my Safari. However, I have FireFox using Rosetta, while Safari is not, so that might have something to do with it.
Other comments:
You can hide in Stonehenge, sort of like the Snow White forest in VMK.
I actually like the history theme, but I am getting a history degree so that may have something to do with it.
The size of the project they are building here is pretty amazing. I am actually really impressed with what they have done so far and the speed at which they are adding things. I think they do want to be careful when promising things to people on specific dates. That way lies madness.
I actually like that we can log in during closing hours and just not talk to or see anyone. Once the game has more features that could be cool -- you could log in at night and decorate your room, or do quests, and then socialize during the day. And as long as you can't see or talk to anyone there's really no danger in it. On behalf of West Coast night owls, I like this feature.
I hope it doesn't get too kid-centric. Family-friendly, yes, absolutely -- but I loved VMK because I am a
Disneyland geek. I mostly talked there with other adults there who were fans of the theme parks, played games and quests, and ignored everything else. It was just my way of getting a little Disneyland into my life far away from the park. And VFK is not Disneyland or WDW, so it's going to have more trouble drawing that demographic, perhaps. If it ends up just being a kids' place I'll have no reason to be there.
I guess I posted a novel here.
(I was wenyeva on VMK during Beta and for a long time after. Then for a combination of technical reasons and real-world issues I couldn't log in for 6 months. When I came back I had lost all my stuff... my beta pin... my quest kiosk... my rooms... so sad. But I still had my money.

So I returned as skycyangirl. I couldn't find my old friends so I never really got back into the social aspect that time; just played Pirates, quested, and slowly built my rooms back up. Now I am wenyeva on VFK.)
