I covered one of sims of this group already, this is the second sim of now three (there were four in the group earlier). Isle of Terabithia has been completely redone and is much nicer than what I remember from my earlier visit. Wear a visitor tag as it is a role play sim, and there were constantly people about when I visited it. Caves and secret areas abound, just what I like to explore.
The sim is rated Mature/Moderate
