Are you trying to advance from island to island as quickly as possible, taking your time on each one, or something else? I'm still on Isla Matanceros. I have a 4 star park, but I want to wait until I've completed each Isla Matanceros dinosaur's genome to 100%, completed all research that can be done (for now), etc. I'm having a ton of fun with this game. I'll admit that the whole power thing confused me at first, but Brett's thread was very helpful. This is seriously an awesome game.
