Well... you have to have more brain cells than a toast to understand the menue. That's true.

Like with any management and sandbox game, I guess. The thinking is not done by someone else for you and a bit of multi-tasking and using your brain is useful in those games.
In the latest review I found they also complain that the game doesn't tell you always what's the problem with your animals if the exhibit gets overcrowded or the animals get deseased. Honestly, if the reviewer wants everything represented to him in red flash-light to pleeeaaasee don't think for himself, I know where to put the menue simulator comment. This game is not for everyoe, I guess - like any other game.
