Jurassic Park: Operation Genesis, I liked this game. If you like games that are like the Sims, then you will like this game. On this game you have to take care of dinosaurs. They need a lot of things to be happy. They need a pen to stay in, and food and water. If you make a pen for a dinosaur you must make sure that they have food, you can do this by placing a carnivore or herbivore feeder inside the pen. You must also make sure that they have water. to do this go into Construction Mode then Environment then select Lake, then put the lake in the pen. Carnivores' hunger, thirst sleepiness, and eagerness to hunt are represented by meters at the top of the screen, as the meter fills up they get hungrier, etc. The Herbivores and Carnivores have different personality traits, for example the Herbivores get stressed if there are not a lot of trees around them so their Tree Stress meter fills up. By putting trees in thier pen it goes back down again. Carnivores get stressed if they can not hunt, by hunting and killing their food this meter goes down. Park Rangers can help you vaccinate your dinosaurs against diseases and also tranquilize your dinosaurs. This game is very good.
