In Dinosaur Island, players must collect DNA, research the DNA sequences of extinct dinosaur species, and then combine the prehistoric DNA in the proper sequence to bring these ancient creatures back to life. Dino cooking! All players will compete to create the most thrilling park every season, and then work to bring in (and keep alive!) the most visitors each season that the park opens.
Do you go big and make a pack of Velociraptors? They'll for sure excite potential visitors, but you'd better ensure a big enough enclosure for them. And perhaps hire some (read: a lot of) security. Or they WILL break out and start feasting on your visitors, and we all know how that ends. You could play it safe and grow a bunch of herbivores, but then you aren't going to have the most thrilling park in the world, will you? (sad face). So perhaps purchase a roller coaster or two and attract visitors to your park another way?
