A new version of an old game.
If you look at the campaigns and the challenges, then most of it is something that you will recognise. This is the disturbing part of the game. For those who went through zookeeper 2, then much of this is just more of the same.
I agree, the designer is a lot better. There is much more to see and to do, so much to enjoy, but no matter what, the challenges are for the most all the same. A new coat for an old design.
Still the many new things make this game enjoyable and fun.
Over time this game could become better and greater, but i think that Microsoft owns the players free additional campaingns to download, because rereleasing the old ccaompaings was not acceptable to me.
