Not trying to toot a horn or anything, but how are so many people having issues with this game? Aside from needing the locations of certain things/animals, there are few challenges in this game. Put a silencer on your guns and beat the story with little issues. The only follower you MIGHT need is Boomer to mark enemies, the rest are useless. Clutch Nixon stuff is a bit hard until you learn the routes. Fishing is a joke, hunting is easy, and if you are farming the achieves like I am, google a bit. So many things in this game are made harder by the players. For the people that have "bugs" and whatnot, record that stuff. Describing it is one thing, but having proof makes your case way better and gives the Ubi staff something to go on when they "might" try to fix something. Help them help you.
It isn't whining when there are some real issues with the game play. Forcing a player to run after a truck or fly a specific plane isn't difficult, it's lazy open world game design and punishes players for trying something different.
Constant animal attacks isn't difficult, it's annoying as feels like a cheap time suck to hide how little there really is to the main story line. Truckloads of cults suddenly popping up out of nowhere and attack in a constant stream every time you try to use a road, not difficult just frustrating. The missions aren't difficult at all, it's simply trying to explore the environment that is the issue. Ubisoft created this beautiful, vast environment and then smacks around any player who wants to explore it.
It's not difficult, isn't just bad open world design where they replace the emptiness issues with a glut of annoyances and unavoidable spray and pray fights. Ubisoft has managed the impossible, and taken all the joy out of blowing stuff up and made it an endless grind.
