I've began to work on Isla Sorna, which will be centered around Dinosaur vs. Human TDMs (Nublar was for RPing more or less). I have school off tomorrow and a full weekend ahead of me. It will also feature pretty simple interiors so I might be able to finish it relatively quickly.
EDIT: It's going to feature two or three pathways from base to base (you get to build the bases) with broken perimeter fences sometimes blocking the paths. You will be able to crawl udner them if you're human or run right through a gap if you're dinosaur. I am taking ideas for other features Sorna should have.
