Real World Back to Vegas???

Why did they decide to do the Real World Las Vegas again? It was the most not-popular season... in my opinion at least. And have these people not moved on with their lives yet? They are in the same place that they can just up and leave their homes and go on this show for 3 months. I am concerned. Im trying to figure out why no body has a job that they aren't allowed to leave. Arissa looks like old... OK not in a bad way but she looks really mature.
