I know that Jurassic World Evolution 3 is not confirmed and is still a rumored game, but this game would be really great (if it's still on old gen consoles like PS4, as I can't afford PS5). Anyway, here are the features I would love Jurassic World Evolution 3 to have in my opinion.
All of the Jurassic World Evolution 2 DLCs being default or part of the base third game - Just like with all of the first game's species (other than most hybrids) being default in the second game, I believe that all of the DLC species from the second game should return as base game species in the third game. I know that this would make the species roster longer, but the more the merrier! With this, maybe a search feature could be improved to make up for this long species list.
Jurassic Park Operation Genesis cosmetics for all dinosaurs originally from JPOG - I know, this seems unlikely, but Jurassic Park Operation Genesis was my childhood game and I would love to see all species originally from that game to have the cosmetics based on their JPOG counterparts, although they should not replace the base cosmetics already in the second (or third) game. If Frontier gets permission from Blue Tongue for their game, I think that this would happen.
Paleo-accurate cosmetics for (many if not) all species - Man, I love paleo-accurate designs, and Frontier has done a great job at some of their feathered dinosaur and pterosaur species like Sinosauropteryx, Yutyrannus, Deinocheirus, Jeholopterus, Gigantoraptor and Utahraptor, whilst keeping the spirit of the Jurassic World Evolution series alive. Although unlikely, I would love it if I could get a 100% genomes for all species, with the paleo-accurate Velociraptors being correctly-sized, feathered, having only supinated wrists, having no shrink-wrapping, and having more logical/plausible behaviors instead of having organized packs that could unrealistically hunt down ridiculously-sized prey such as hadrosaurs or sauropods. However, their inaccurate counterparts should stay, for those who have nostalgia or prefer inaccurate species.
Most if not all species should have "Lux" variants - We got the "Lux" variants for Styxosaurus, Parasaurolophus, and hybrids, so why not other species having them? I would love a beautiful nighttime park full of glowing dinosaurs, synapsids (Dimetrodon and Lystrosaurus), pterosaurs, and marine species.
Breeding and babies - I think that this feature would be nice to have for a proper Site B mode-styled experience, as well as for those who want to have their species breeding in the parks without having to reclone them.
More attractions - Currently, attractions are great, but they could be more. I would love the petting zoo (the best thing about the Jurassic World movie) added, assuming that the afromentioned breeding and babies exist for the third game, while also containing small herbivores and (if their behaviors change in petting zoos) small scavengers like Compsognathus, Moros intrepidus, and Sinosauropteryx, just to name a few; I want this experience to be accessible to first-person mode, not just the park's guests. Other attractions like the Cretaceous Cruise and balloon tours would be cool too.
Allow aviaries and lagoons to be connected to dinosaur fences - It would be great if we could easily get dinosaurs into aviaries without modding, and have lagoons connected to dinosaur exhibits, so we could see interactions between marine reptiles (and fish like Dunkleosteus and Megalodon) and dinosaurs. With this feature, we could finally get proper semi-aquatic species like Deinosuchus added.
Make aviaries better - Aviaries are just not enough and deserve better, not only in species diversity, but also the aviary sizes and such. I think that there should be giant aviaries to house larger species such as Quetzalcoatlus (that way, the quetzes aren't so cramped up and so their flights aren't so derpy), as well as open-air aviaries (for a more naturalist aviary without pterosaurs (or, if flying dinosaurs get added, Microraptor and Avisaurus) escaping) and invisible aviaries (aviary counterparts of invisible dinosaur fences).
Sauropods and hadrosaurs should be able to fight back against predators - If you could tell right now, sauropods and hadrosaurs were not just walking meals for predators to hunt, as they were able fend off predators in real life (a huge Edmontosaurus could easily beat a T. rex to death, so seeing an Edmontosaurus easily killed by T. rex seems like an insult to the real hadrosaurs in general). Heck, (most) sauropods in the game are based on their real life counterparts, which were too big for most predators to bother, and the raptors being able to hunt a huge sauropod in packs is totally absurd. That's why there should be an option to turn on sauropod/hadrosaur defense to enable them fighting off most predators (I would love to see my hadrosaurs fighting off large predators).
The cohabitation and comfort settings should be changed - I really would want Jurassic World Evolution 3 to upgrade their cohabitation and comfort settings in a variety of ways in the sandbox mode, such as the ability to have all herbivores be able to cohabitate with each other while also have carnivores not cohabitate, and vice versa. The comfort settings should also separate herbivores and carnivores, so I could have the carnivore fights while also have herbivores being peaceful in the game. These two setting changes should also apply to small, medium, and large species of both herbivore and carnivore categories, so I may only have large carnivores fighting while having the small carnivores always running away from large predators instead of fighting back (almost reminiscent of JPOG).
More natural scenery - I think that we should get more types of natural scenery such as waterfalls, tunnels, and natural lagoons, just to name a few. The natural lagoons should be able to connect with lagoon hatcheries for a more naturalistic aquatic environment for my aquatic species.
First-person survival mode - As you've seen, we all have a first-person mode in Jurassic World Evolution 2, but it is so limited and it would be better if there were more to it. The first-person survival mode option would make the experience more thrilling and terrifying at the same time, and the first-person survival mode could give us tranquilizer guns as defense against dangerous species (aggressive herbivores and hungry carnivores), while it also make the first-person mode more useful than just checking things up close.
Water depth editing ability - We should have the ability to deepen or raise water depth, so we could finally have swimming dinosaurs (and synapsids if possible) in the game, and possibly to contain certain species (like how apes in many real life zoos are surrounded by water to prevent their escape).
Bring greater food diversity to the game - There should be a higher diversity of foods in this game, such as more live prey feeders (cows, pigs, and deer, for example). I believe that the first Jurassic World Evolution's herbivore feeders should return (in addition to natural plant food items from the second game) to make housing and feeding herbivores easier and so I don't have to unnecessarily keep replacing food from one herbivore species with another separate food for the other herbivore species.
Have pterosaurs the be able to walk - A bunch of people have criticized the game's pterosaurs for their inability to walk, even the ones that definitely could've walked in real life such as Quetzalcoatlus. That's why I've suggested this feature to be added to make the pterosaurs seem more alive.
Better fighting mechanics/ai - Currently, carnivores, no matter how big or small, fight each other and go around in circles during combat, so this must be changed for the better n order for these fights to be more realistic. I also think that there should be an option to make predators smaller than large carnivores to run away from large carnivores (a Carnotaurus running away from a T. rex is a much more realistic scenario than them fighting each other). Also, no dinosaurs or other species clipping through each other please!
Customizable hybrids - We are all tired of hybrids due to them being paid DLCs (other than Indominus or Indoraptor, or possibly Scorpius rex if that's a base species for the third game like the former two), so I think that there should be a menu where we could create our own hybrid species, so we can finally have Spinoraptor, Stegoceratops, Spinoceratops, and Ankylodocus (JWE1 variant and JWE2 variant) in the game already without having to pay for them, as well as creating our very own hybrids (making many designs like the Ultimasaurus a possibility).
I hope you like my ideas for a possible third game to Jurassic World Evolution.
