Looks exactly like Far Cry 3/4 just without guns.
Which makes it shit. The whole point of Far Cry 3 and 4 is to do crazy shit. FC4 did a great thing by starting to move even further to the silly end of the spectrum and allowing you to do even more dumb shit in the game world.
I was hoping the next game would just keep adding more fun and stupid shit you could do. A basic minimalist story a la FC2 and no "you are leaving the mission area" horseshit are on the wishlist as well but seeing as this Ubi that seems unrealistic.
With this shit it looks like they stripped away certain elements and all they give you in return is the animal BFF. It's funny that such a drastic change is coming from Ubi out of all places, the guys that are known for repeating the same crap more than any dev in the industry at this point.
TLDR: FC3/4 without guns, explosives, a wingsuit, vehicles, or fun. It's more like FC3/4 where you are forced to use the shitty bow, stealth, and your feet for the whole game. It's shit.
