When I first saw the game I had so many questions at the end. It's was sad and happy, the choices were very difficult. It was like Minecraft StoryMode expect that the characters dies in any choice you make. The ending was marvelous:
Kara gets to be a mother to Alice
Markus made peace with humans
Connor is like a son to lieutenant Hank Anderson
What I learned from that game was you shouldn't let others tell you what you are.
