So I was surfing the net (as one does) and found a little article I thought some of you would find interesting, you can find it here. I have included some quotes I found interesting.

"...when you press the random button, instead of actually getting a random piece of dress, you actually get clothing from some other players. That's loaded from the database of that particular hotel..."

"...Like the biggest instance that we have right now... The peak is I think more than 20,000 players concurrently..."

It's a good interview, I recommend taking the time to read though it.
