Ark has come along way since its release. At first (Ark) was not very promising. With terrible optimization, ark was nearly unplayable. Now that ark has been released for over a year now; it has had numerous updates and additional maps that have made the game great! with 700+ hours on ark, it is a game i definitely suggest for those into survival games.
