If you mean Guests not sticking together in The Walking Dead like Herds, I absolutely agree. This Picture is unbearable to look at. Luckily it isn't that bad in my current Zoo yet but they should really not all be in the same Place at the same Time
Agree. If your zoos are too small you're likely losing money If they're really popular you get this eyesore, which also causes the game to run more slowly. I'd be fine with a "group" being represented by a single person on screen.
The Game can even run smooth with a giant Number of Guests but for this it is necessary that they are well distributed throughout the whole Zoo which often isn't possible until they change it. Also it's just unrealistic. Who would want to be in such a huge Group?
