I don't know how this game is fun let alone addictive, I installed over 10 mods for it and I can't pick the game back up. I mean it's SOOO boring that even the mods I was using didn't give me some sort of urge to play it again. I've been playing older and way better games worth my time since then so it doesn't matter.
I actually had fun and found it addictive. In the beginning. While the whole thing was shiny and new and all that jazz. I mean, I thought we were on to something here... The first thing that hit me (aside from the whole dialogue/voiced shit, obviously) was when I couldn't talk Kellogg down. Then I thought "Wait... You mean my only option is to kill this guy?". Then I found a nailboard that somehow froze people. The I started noticing how much of the game's content was really only radiant shit (which I refused to believe at first, in a comedic manner).
Finally, I was just thinking, let's finish this thing and at least see all the choices and endings. And boy was I disappointed... All that work for a "Yay, you finished it! Keep playing if you want, nothing's really changed".

I thought the voice acting was great and hating the game just because the main character has a voice actor is pretty dumb since the chosen one talks in Fallout 2 except you don't hear his voice. Voice acting is the least of all problems this game has they actually got the voice acting right. The problem is they made Fallout 4 into a generic boring game where none of your choices matter in the end and the game gets old really fast. It's the same crap where people hate the game just because it's not ismoteric. The game sucks because it's a piece of shit not because of a graphical change or camera view.
I'm going to have to go ahead and say that the male protagonist voice acting was
awful. Maybe the female character had a better voice actor, but the male was clearly given his lines and asked to record them without knowing anything about Fallout or the game itself. The lines were cut and pasted together to form conversations such that dialogues have incredibly obvious changes in tone of speech, or the lines just glitch out entirely. Nothing flows and I have since stopped playing Fallout 4 and gone on to games with actual voice acting.
It is the worst voice acting and dialogue I have ever seen in any video game I have played, and I have played almost every major video game you might compare this too.
Games with actual "great" dialogue and voice acting:
Deus Ex HR
All previous Fallouts
Elder Scrolls (Skyrim had stupid writing, but the voice acting itself was fine)
All Bioware games
Wasteland 2
Pillars of Eternity
All Witcher games
I could go on...even Deus Ex 1's budget voice acting was better.
"WHERE'S MY SON?!?? WHERE?>>>WHA WHA WHAR SHAUN????" is "great" voice acting? Ok.
You want voice acted protagonist? Fine. But if it is terribly voice acted and the lines are cringe-worthy 90% of the time, I'm not playing the game for 100 hours.
If it's a 3 hour movie I can forget 1 bad voice actor, but in a 75-100 hour game I'm not going to be saddled with terrible dialogue and acting. So yea the voice acting is actually a pretty big deal since they decided to force a voiced protagonist on us and then made it really bad.
