I really liked trying out unlimited traits with my dinosaurs in sandbox mode. There is fun to see what would end up being the three traits assigned to your dinosaurs, but it was just as exciting to incubate animals that would have up to 10+ traits at a time. Not only does the sheer number of traits make containing certain species over others interesting, but it allows for traits to not be completely absent after modyfying the chances of 3 traits to be the more common. You take in the good with the bad and can't completely clear up all negative traits of dinosaurs via modifying the genome. It could lead to interesting playthoughs if players enable this setting in Custom Challenge Mode.
Unlimited traits is one way to attract players to play the Custom Challenge.
Regarding dinosaur species that start off with unfit trait, be sure that they have the fit trait. It is not just the ones with unfit, ensure the species' chances of getting the fit trait to 100%. It would be better if hunters and runners have the fit trait.
If the dinosaurs' lifespan is set to normal in the gameplay conditions, be sure to have the dinosaurs having "long-lived" trait.
Sauropods, medium-sized and large carnivores have to have both "humble" and "social" traits to lower their environmental needs. However, there should be one Acrocanthosaurus and one Giganotosaurus in their respective enclosures. Even with those traits, two Acrocanthosaurus and two Giganotosaurus require two live prey feeders. It would be better if beef cattle are included as alternative prey to be dispensed. Therefore, two Acrocanthosaurus and two Giganotosaurus with the two traits can choose to hunt either goats or beef cattle.
