From the footage and screenshots we've seen so far, it would appear that terrain textures are limited by the map's biome like in Planet Coaster. So if I chose to play in the North American map, I wouldn't be able to have the yellow grass of the savannah biome, or a deep jungle terrain option. While I love all the creative freedom the game provides otherwise, I really wished this limitation Planet Coaster and Jurassic World Evolutions had didn't carry over. The screenshots we've seen shows how an African Elephant looks natural in a green grass European/American zoo but I'm not sure if all animals apply to this. Chimpanzees for instance look a bit weird in the savannah biome. It is still fitting relatively, but a Polar Bear would be very odd. At a minimum I hope we can get the same Sandbox "Choose your textures" option Planet Coaster eventually added. Its just a shame that I'd have to give up some of the multiple sand/rock options in my Savannah zoo just to add a few jungle/tundra terrain options.
