I had beaten this one a long while back. Computer crashed, had to re-install, so I'm stuck on this one now. I get everything else done, but guest happiness. All of the animals are very happy, it stays at about 98%. I tried what I read here, use restaurants, and it worked to a degree. It seems that I could keep guests happy using tons of food stands in my game before the computer crashed. I even downloaded the happy guest hack, doesn't seem to work. I re-did my zoo a few times, used different approaches. This one is driving me as crazy as the pred/prey scenario (which I still haven't beaten :angry ). I have lots of scenery, statues, ect. I can get it as high as 80, then it goes straight down the tubes. The thing is, nobody is angry, hardly anyone is hungry or anything else. When I read people's thoughts, they just keep saying that the animals look overjoyed, isn't that pretty, or whatever. Does anyone have any clues? I'd really appreciate it!
