As I understand it this is the fast and loose version of 'Survival Evolved.' What I mean is that you resource gathering is significantly increased, giving you the potential to create tools and shelter etc and eventually tame dinosaurs which is very cool, a lot faster than in the aforementioned game. There is a great element of danger knowing that your enemies are somewhere around also developing ways to kill you. This game is best played with a friend/s. I played this with a friend and it was great working as a team to build what we needed to develop weapons and tame dinosaurs. We never won a game as there always seems to be someone on there who has a T-rex or Spinosaur and/or a rifle, while we had bow and arrows and lower level dinos. However it is such fun it is definitely worth playing this game, especially if you have a friend and it's on sale. I was lucky enough to get it for free.
