Its become clear very quickly that the game has quite a lot of ethics built in. Great for kids but pretty lame for a nut job like me. You cant sell babies so no puppy farming behind the scenes. Booo... You cant drop lions into springbok enclosures for that authentic African experience...boo and you cant drop zoo guests in with the tigers..... boo... (ive tried all 3). Heck the keepers just walk around among my Grizzly bears like its his back garden. Really wish the animals ate people, especially keepers and those annoying guests that pull faces at the animals.
