I assume you mean Jurassic Park: Operation Genesis. It would be a good idea to put in the full name so people know for certain what you're talking about.
Anyway, all I did was play a demo. I never bought the game. I had other things to do, and if that wasn't the issue, money was. The demo was okay, though it got boring pretty fast doing the same 2 missions, and while I could modify there was very little I could do since it was just a demo. Though I did have fun writing down stuff with the island modifier or whatever it was.
The most fun I and my brother had with the demo was killing the predators with the car and then taking pictures of their dead bodies. We both got a kick out of it because in that mission, you are supposed to take pictures of live predators in action.
He and I did have plans, though I doubt we could do them. Still it would be hilarious if we could. A few ideas included making the guests wear bacon-flavored necklaces, placing the tyrannosaurus pen right next to the visitor's center, and using only dirt lines to separate the raptors from the guests.
