I agreeThe dinosaurs should be given unique and different personalities like the animals have in the new game of frontier planet zoo.
What if the dinosaurs genetics influenced their personality? For example, if you modify your dinosaur with aggressive instincts your dinosaur will be... well... more aggressive, obviously. Like, if you have two trikes with that modification, they'll both fight for the title of alpha more often.
That's what I thought the gene mods did when I first played the game and was disheartened when I discovered that all it did was increase the dinosaurs rating, cost, and lifespan. To bad too because there is SO much potential with the gene mods with regard to the behavior of the animals.
