1. Customizable maps (like in JPOG)
2. Bigger islands
3. Maps of entire islands
4. Return of JWE and JWE3 maps
5. More maps
6. Docks & airports
7. Better terrain tools (including water depth and , to name a few)
8. More natural scenery (including, for example, usable natural lagoons to house lagoon species in naturalistic environments, as well as having fog stones to produce fog, geysers and scenery mini-volcanos, and many more)
9. More path sizes
10. More feeders (plus the return of JWE herbivore feeders and JWE2 piscivore/carnivore feeders)
11. More gates and fences (including glass fences and gates as an alternative to viewing galleries)
12. More options for amenities and restrooms
13. More attractions (petting zoo, Cretaceous cruise, and balloon tours, for example)
14. All species from JWE2 (including the expansion packs and DLCs)
15. More dinosaur, pterosaur, and marine reptile species (especially HaČeg Island fauna (not just Hatzegopteryx))
16. More skins
17. More cosmetics and variants (including possible paleo-accurate variants for some species, including Velociraptor and Ankylosaurus, to name a few)
18. Much better species AI (more complex behaviors and better, more random fight animations)
19. Pterosaur walking and social animations
20. Better first-person mode (including the dinosaur attack feature)
21. Customizable hybrids (albeit with only about half the non-hybrid species available for hybrids to use; there should be a naming system for us to name our hybrids, as well as a customization for AI, scales and/or feathers/fur, size, diet, colors, patterns, and sounds)
22. More non-dinosaur non-pterosaur non-marine-reptile Mesozoic species
23. More Paleozoic species
24. Cenozoic species (aside from Megalodon)
25. An option to prevent carcasses from disappearing (to allow us to have natural carcasses that are not from feeders)
26. A much better cohabitation feature and an ability to edit cohabitation (so we can have, for example, all herbivores like and cohabitate with each other, unlike the carnivores)
27. Better guests and behaviors
28. No terrain constraints
29. No building constraints for decorations, fences and paths
30. No dinosaur clipping into each other
