I don't own that game. But I just tried it out using family share on steam. Little sad that you have to kill other players as there is no AI though..
Anyways I do personally love dino's. That said, are you aiming for it to be like Isle or just the Isle dino's in MC? I did read the comment about being both mobs and playable bit. But that does not answer really what I am wondering per say XD.
