I love the game, I've played it a few times now and it's still challenging even for someone who plays it constantly. Its amazing how much detail is put into a single creature.
P.S. This is just a suggestion for the Developers of the game, but i think it would be really cool if at the end of the game after you watch all of the subtitles and stuff that their would be an option to play as Trico, with her family, or something like that. I just think it would add another element to the already amazing game. I would play it all the way through multiple times to get that as well, if it was added.
