We have taken it upon ourselves to provide a change in ISS, which will hopefully offer many more options for people to post about. Our idea is this:
Humans once again come to Sorna with the intention to capture dinosaurs, but not to make a park. Their purpose is to sell the dinosaurs to the first person they find, being a modern equivalent of pirates. Anyone who wishes to participate would have their characters captured, and taken to a new setting; A post-apocalyptic New York City.
Imagine I am Legend. Just with dinos and without the zombies

Grass pokeing up out of cracks in the streets, cars strewn everywhere. Caves replaced by houses and cafés.
Essentially, dinosaurus adapting to an urban environment, using the city as their new jungle.
There would be zero humans in New York City, after the dinosaurs' captors leave, due to chemical warfare cutting human population down to the hundred thousands across the globe. The bridges in New York City would be destroyed, forcing the dinosaurs to remain on the island city, but the buildings themselves would be intact. Plants, with no one to control their growth, would grow throughout the city, in lots, gardens, etc. The streets would remain the same, but there would be small patches of forested area in large lots throughout the city, which, coupled with Central Park, would support the herbivores that lived in the city.
It would act the same as Sorna; no dinosaur could leave the island, even to go back to Sorna. People can choose to stay on Sorna, or move to NYC, but CAN NOT go between the two. The dinosaurs in NYC would stay there for a year (Not RPG time, give or take a month or two), before returning to Sorna via another event.
The population, however, must be controlled because of the terrain. Weather wouldn't effect the dinosaurs; this is the distant future, in which global warming as taken effect in New York, so no more snow would fall in the city, and would remain hot and humid. This is our plan for the dinosaurs' actual population:
Large Carnivores (Tyrannosaurus, Spinosaurus, Carcharodontosaurus): ONLY Character Dinosaurs, no NPC varieties of these dinosaurs would exist in the city for balance issues.
Medium Carnivores (Allosaurus, NanoTyrannus, Ceratosaurus): Few NPC Dinosaurs of this variety will be present in the city to allow for pack animals such as Allosaurus to form packs (Packs must have at LEAST one Player in the pack itself, so there would be ZERO NPC packs present).
Small Carnivores (Raptors, Coelophysis): NPCs would be present in the city, to allow the formation of packs, but once again, AT LEAST one player character must be in a pack, if one wishes to create one. No NPC packs will be present. (creatures like compies are exempt from this)
Herbivores would be much more widespread, for reasons which will become obvious when the move happens.
Here is a basic map of the general area. It also shows the limits placed on where the dinos can travel.

With that said, we would like to ask the members for their opinions. Do you think you like the idea/would like to participate in it?
