Ok, so I'm not that great at completing senarios. I usaually get half way through and then give up. But I've been trying really hard to complete the Endangered Species Senario, where you have to make a 5-star zoo with all endangered animals. I can get my zoo to four stars, but after that, I can't seem to gain anymore stars. Last time I tried, my guests were happy, my animals were happy, my exibihits were educational, I had a lot of animals and different speices, but I still couldn't get to 5-stars. Does anyone have any hints to complete this senario?
