I started a zoo again, and this is what I've got until now:
I first made the "visitor area", before my first exhibit.
I then spontaneously decided on the Tundra Gold-Winged Dragon and the scimitar Oryx.
The next exhibit was devoted to Paraceratherium (the desert type, which I like more than the Savannah type).
I at first tried to keep Rhim Gazelles and Goitered Gazelles together, but their needs are not compatible, thus, I separated them quickly.
