[quote name='TooPoor']How's the coop portion?[/QUOTE]
the coop is fun with friends, but its nothing special. same for the multiplayer (well im a battlefield fan, so im biased haha).
the campaign however is amazing and intense (I WANT MORE OF IT). the main character grows on you and youll be rooting for him throughout his journey. unfortunately though, the intensity somewhat dies if you deviate from the story mission, but theres just so much to see outside the main story so why rush?
my advice is that you 100% the game by doing every side quest as soon as you see them, and by collecting the collectibles (think riddle trophies from arkham city, but in an island), so youll see everything that the game has to offer (locales, animals, towns, etc). immerse yourself by reading the things that are readable in the game so youll learn about the island and its people. lastly, play on the warrior difficulty (otherwise its too easy).
take your time. if you want to explore and hunt, do so, but dont take too long doing it, because the you will see the whole island if you try to get all the collectibles, and you will get all your hunting needs and materials from the hunting missions. might as well make your exploration and hunting count towards something and get rewarded for it.
on a side note, if you havent played deus ex human revolution, i highly recommend that game. i have this sudden urge to go back to deus ex for my 2nd playthrough after beating far cry 3 last night. its just as good. though deus ex is a keeper (the game is much longer)
