I wish these voice overs were available in sandbox mode too. Maybe an option to turn them on or off as well as one to reset them as I understand they only play the first time you release a member of each species. Sandbox just seems too quiet and lonely. I thought turning on contracts would help but even those are muted for some reason.
I don't get what you are saying about this turning them on or off thing. Normally after the completion of the Science Mission in Isla Matanceros, Owen Grady would have a say when another Triceratops was released. After the Security and Entertainment Missions in Isla Muerta, he would have a say when another Velociraptor was released.
It wasn't a problem in the Jurassic World era challenge mode.
George Lambert having a say about the Ankylosaurus along with Dr. Kajal Dua saying about the Baryonyx, Camarasaurus, Chasmosaurus, Deinonychus, Muttaburrasaurus, Parasaurolophus, and Struthiomimus were only available in the Jurassic World: Evolution campaign.
Shouldn't there be a character in Jurassic World era have a say about the Compsognathus and Pteranodon?
