From my view I can only talk about my impressions of the videos I saw about the game. So some "bad thing" won´t (probably) match with the final Game.
What I like so far:
1. the Game looks gorgeous. The models, animals, skins and the scenery are wonderful to look at.
2. JEFF GOLDBLUM, BD WONG, BRYCE DALLAS HOWARD are part of the voice cast! That´s amazing and much more than I expected!
3. The Bioengineering part looks like its pretty cool! Can´t wait to find out more about this!
4. The Gameplay I´ve seen looks like the players can lost themselves in it! And I love it!
5. A huge collection of animals is in the Game. About ten more than I expected.
6. Free DLC !!! Thank you frontier for the sympathetic Decision!
7. The whole rest, which is not included in the second list!
What I don´t like:
1. There´re too many animals, that are too close to another one IMO, what gives me the feeling like I´ve got a handfull of clons (Galli= Struthio, Tricera= Chasmo, Corytho = Tsintao, Velo = Deino etc.)
2. It´s seems like there aren´t many possibilities to equip and customize the park. Decorations, Fences, attractions etc.
3. It seems like there aren´t many possibilites the animals can Interact with eachother and their environment. No logs, no stones, no prey dolls, toys etc.
4. It seems like there aren´t terrain tools, that changes the ground. My concern is, that the enclosers could look all the same ... all grass, same plants, low waters
5. There´re some things, that reduce the "Illusion" and the "Realism" in the game in my opinion. no successfull attack on the jeeps and personal for example. No Day and Night circle. No Killing of dangerous animals, probably the need of an feeder for the herbivores and no natural barriers as fences etc.
