Great Story. Tons of gametime. Worlds are too big and its not clear where to go.
However, the game's massive enviroments make things terroryzingly large when you get lost on the wrong side of the planet due to the lack of a convenient navigation system. Additionally, there are times throughout the game where you are stuck in dialogue scenes then running around through the buildings then discovering you went to the wrong place for hours. This greatly slows down the gameplay. I couldnt quite manage to make it through the first time and I tried again and quit in 3 hours.
Chances are, youll like the game, but it's these 2 points that wreck the game for me. Its too long to rent so Ill say its worth a 'borrow'.
