Hi, this is williezk, one of the main creators of the Revolution Universe.
I played this series as it came out, and I have to say it's already shaping up to be good. IMHO, Part 1 is much better than Part 2, as you are free to explore the majestic park and see all the animals (especially one of my faves, the Platybelodon!) Not only does it incorporate prehistoric animals from Earth, it also incorporates ancestors of other Revolution Universe alien species (such as the Kleekoonanonis¹ and Tyleturanulas²).
Spoilers ahead!
Part 2 is the slightly worse of the two so far, as it is a (difficult) action story of some animals attempting to escape their exhibit for reasons untold. It can't quite live up to the majesty and free will of its predecessor, and the watercolor filter (which eme12 says is to see the world how an animal likely would) makes for a rather jarring visual experience. The fact that the fights are quite underbalanced (with only one chance to heal up) doesn't make things better.
Overall, a good adventure series that shows promise. I'm excited for what else will happen to this park.
