Dinosaur Cohabitation Amendments for Future Major Updates

Dinosaur cohabitation
  • Parasaurolophus and Maiasaura are now friendly to each other
  • Pyroraptor now dislikes Scorpios Rex and Indominus Rex
  • Australovenator now dislikes Scorpios Rex

Since Update 5, there have not been any changes in dinosaur cohabitation. Honestly, it still needs work.

why JPOG holds up so well

@Ilokelesia Dinosaur cohabitation is another factor why Jurassic Park: Operation Genesis holds up so well.

Cohabitation Balance
  • Adding a Likes relationship between Hadrosaurid and Ornithomimosaurid
  • Adding Likes relationships between specific dinosaurs that dislike each others' categories:
    • Apatosaurus and Brachiosaurus
    • Camarasaurus and Brachiosaurus
    • Chungkingosaurus and Gigantspinosaurus
    • Gigantspinosaurus and Huayangosaurus
Cohabitation Balance
  • Added a Likes relationship between Hadrosaurid and Ceratopsids
  • Added a Likes relationship between Ornithomimosaurids and Ceratopsids
  • Ceratopsids can now cohabit with other Ceratopsids, with certain exceptions
    • Triceratops can't cohabit with Styracosaurus, Torosaurus or Sinoceratops
    • Torosaurus can't cohabit with Styracosaurus, Pachyrhinosaurus or Sinoceratops
    • Styracosaurus can't cohabit with Sinoceratops
    • Sinoceratops can't cohabit with Pachyrhinosaurus
    • Nasutoceratops can't cohabit with Chasmosaurus or Pentaceratops
    • Chasmosaurus can't cohabit with Pentaceratops
Which makes it so that the cohabitation preferences of various species in the game don't make any sense. They should've adopted a system like Planet Zoo where interspecies enrichment/cohabitation preferences are based on animals that a particular species would actually coexist with in the wild. For example, all the herbivores of the Hell Creek and Lance Formations should be comfortable being housed together. Same holds true for herbivores of the Morrison and related formations. The system they have now is so generic and illogical it boggles the mind. Carnivore, pterosaur, and marine creature cohabitation preferences are even more illogical when you really examine them. Point is, for your suggestions to work, the entire interspecies cohabitation system needs a complete or near-complete overhaul to reflect my statements above. Otherwise, it does not nor ever will work the way it should.

Carnivores

  • Majungasaurus cannot cohabit with Qianzhousaurus
  • Albertosaurus cannot cohabit with Carnotaurus

Abelisaurs occupied the Earth's south hemisphere whereas the tyrannosaurus reigned the north. It would be better if the two different types of carnivores fight each other for food and territory.

Regarding Allosaurus, let its relationship with Ceratosaurus slide due to sharing the same dig sites. However, it is best that Metriacanthosaurus dislike Allosaurus due to different dig sites.

Currently, Majungasaurus and Carnotaurus like each other due to being the same type. The same can be said for Suchomimus and Baryonyx. It would be better to have these likes relationships like those two:

  • Acrocanthosaurus and Carcharodontosaurus
  • Qianzhousaurus and Albertosaurus


Herbivores

Currently, ornithomimids and hadrosaurs likes almost every type of combat-capable herbivore, but there is an exception. What do you say about filling that gap by making ornithomimids and hadrosaurs like pachycephalosaurs?

What do you say about having the relationship between stegosaurs and combat-capable pachycephalosaurs as neutral? As a trade, these species of pachycephalosaurs like ceratopsids. As an exception, Homalocephale likes all types of combat-capable herbivores as it needs those for protection.

It would be better that the specific species should like each other due to the fact that they share the same dig sites:

  • Dracorex, Stygimoloch, and Pachycephalosaurus can mutually cohabit
  • Huayangosaurus can cohabit with Chungkingosaurus
  • Gallimimus can cohabit with Deinocheirus
  • Camarasaurus and Apatosaurus like each other
  • Diplodocus can cohabit with Camarasaurus, Apatosaurus, and Brachiosaurus
  • Pentaceratops can cohabit with Alamosaurus
  • Torosaurus can cohabit with Alamosaurus

This thread also serves as a follow-up of this existing thread


In Update 4, I find the likes relationships of Pentaceratops, Styracosaurus, and Torosaurus is more like "add legs to a drawing of a serpent". To put it simpler terms, these likes relationships are not necessary and they only spoil Jurassic World: Evolution 2's dinosaur cohabitation element. Styracosaurus liking Chasmosaurus is already good enough. Here are the amendments for the better:

  • Styracosaurus cannot cohabit with Nasutoceratops and Pentaceratops
  • Pentaceratops cannot cohabit with Pachyrhinosaurus, Torosaurus, and Triceratops
  • Torosaurus can cohabit with Triceratops

From this particular article,


It is revealed that Maiasaura is recently discovered in Oldman Formation of Alberta, Canada. What do you say to the following likes relationships?

- Corythosaurus can cohabit with Maiasaura and Parasaurolophus

Pterosaurs

Currently, Geosternbergia's like relationship towards Pteranodon is one-sided. What do you say to make that like relationship mutual?
