I think this game is too complex. It might be a good thing for some, specially for the most creative who have a lot of patience. For the people who want it simple I don't recommend this one.
The graphics are good; There are a lot of animals but things aren't that easy to decipher. And the path system sucks! I wish I could make paths as easy as in Zoo Tycoon but I simply can't unless I use some sort of gaming hack
