I have 200 hours into it. I would say it is crazy fun but the PVP servers are filled with Chinese that hack and it has been a problem forever. They find ways to walk into bases or simply remote claim ownership of your dino's. I have been looking for a private PVP but I kinda gave up since everyone I played with quit. PVE could be fun but PVP would be the best if you were not under constant attack. Your character can be killed even when you are not in the game and you lose everything on it.
