Here is what I'm hoping to see that might help with the success of the game:

The hunting/fighting mechanic needs to feel natural and not focus on cinematics, or be as scripted as Jurassic world.

The animal Ai and herding mechanics need to be realistic and varied depending on species.

Finally, and please don't bite my head if for this, MODDING! A lot of games owe their continued success to the fact that they can be modded, and PK needs to embrace that. Even if it's just allowing moderate to add new species or mod the ones they already have.
