I finished the main story, loved how it has been told and pretty much all of the ideas implemented in game but… bugs are all over the place. objectives didn’t trigger to me in a lot of situations so i had to load game back couple of times loosing progress and do it over again, game crashed a few times.
Save system which i presonally like very much is also fucked up on PS4, when you exceed some limit of saves (± 30h of play) the game won’t save game at all untill you delete earlier savegame files.
i think everybody forget to mention about fucked optimization on PS4, textures are not loading. framerate during fights often lowers to an unplayable level, missing NPCs, NPCs who got objective behind unlockable door, fucking titanium bushes which get you stuck in almost every trip out of the villages, riding a horse like it was a steamtrain and above all LOADING SCREENS before any conversation. It is driving nuts when you come to store interact with a guy (wait 10sec) - repair your eq, interact again (wait 10sec) sell stuff, interact (wait 10sec AGAIN!?) talk about quest 
But what really dissapointed me is the fact that after 20 hours played (mid-game) the enemies became 1shot1kill who can do shit to you and the game becomes non-challenging as hell. After completing main story majority of side quests are impossible to finish (objective markers out of map boundries, empty cities, npcs missing, bandit camps missing, dialogue options missing) so i suggest you to leave it to the very end.
Lockpicking - people complain about it very much, for me its okay but i cant understand why there are very hard locks which the game wont let us open only because the game wont let us few of the perks are messed up and dont work properly (wearing leather gloves decreases our light armor bonus or perk which gives us 1+ stats if we eat certain amounts of food is always enabled no matter if we are starving)… so after a several dozen on hours game starts to be and easy as fuck and in consequence boring. No bandits or even guards threaten us i could go to sassau and kill every single person. still live and breathe and head for further killing sprees lol
I wonder if you are hoping for a quick patches witch would make the game more playable and fix major issues any soon?
