Buy it if you love animals and want to just casually watch them play around, grow and breed in habitat you yourself designed.
Do not buy it if you cannot tolerate occasional crashes, annoying (but not really game breaking most of the time) bugs and shallow management simulator.

Planet Zoo is amazing game: it is meditative and beautiful but it is not a proper zoo management simulator even if it is looks like one. It is very simple given you have some patience at the start and there is not much to do. Sure, there are some animals to see and quite many of them too. But they are not that different or even hard to manage. Stuff management ends with zone of work and some training and while research exist here it is mostly to keep players from munch through content too fast.

P.S. It is possible that there are some actually hard scenarios in challenges mode, I did not try it yet. So take "casual" with grain of salt.
