interstingly new?
Good: The gameplay is smooth. easyish controls. very cool how you can make dino's kill each other or other people. the bow just is the coolest and killing dino's and people with a knife is cool just saying it. dino's have good AI. many guns that seem quite powerful makes changing from bow to gun feel differnet. Graphics is not amazing but its still just right.
Bad: the story is quite bland. ending is no very good at all. some glitches with the AI and human AI is just crap. cant really sneak up to people which makes it 1 sided game. some missions are jsut plain stupid or frustrating. many dino's but most of them are the same. making things boring quick. boring and crap multiplayer. a lot of lag. A LOT OF LAG!!!!!
Conclusion: well its worth renting. not many people will be playing the multiplayer anyway cause its just a waste of time. some missions are no brainers and some are annoying as your neighbour.
