If you’re a fan of the original films, then this one’s for you! The Jurassic Park Expansion mod essentially makes the dinosaurs (and a few other things) more visually consistent with how they’ve appeared in the original trilogy of films and other related media. This is another skin and texture mod, but one with a specific purpose. Please note that you will need to start a /new/ park to use this mod, as it will break existing saves and possibly the game itself, forcing you to wipe and reinstall. This is a simple mod with a simple purpose – more space! Expanded Islands makes the landmass bigger so there is more space to build up your parks.
There’s not much more to add about this one – it focuses on the environments, rather than the dinosaurs, and as mentioned above there are plenty of mods that add in new dinos or reskin existing ones so you’ll want to use this in combination with something other mods. This mod focuses purely on environmental textures and objects, making them all look prettier, and even improving rock formations by making every rock its own in-game entity, which as of the most recent update allows for more creative environment building, letting you create things like caves. These are the best Jurassic World Evolution mods:
