At the time of this review i have only played the single player part of the game without trying the online one.
I guess i could rant a lot about this game but i will restrain myself and keep it really short.
Game is trully magnificent and i believe everyone should try it!
Even if you aren't enchanted by the open world aspects of it (i certainly was) and all the things you can do and find, you should really experience it's story because it's well-written and directed.
Definitely recommended!
