Idk why people said that it is so childish to pick dinosaurs when technically we are all a little bit or a "bigger" bit children cause we play a video game. This is what is fun about video games that we merge together "mature" ourselves and immature childish hobbies from our past . Cause i think that at the base of it we all stay children just maybe "experienced" children . I respect both choices or not just thought that the dinosaurs looked more goofy and this game is all about that . :D
