These are my impresions of the game.
1.Gameplay
We can officially say that Fallout turned into a shooter, 80 % of the time it's just running around killing all kind of things.
Of course you get your power armor in the first 30 minutes, after that the game itself became boring for me.
The AI is a terrible mess (just as i predicted in the past) and fighting stupid bots is no fun.
2.Dialogue
Look at the dialogue in F2,F3,FNV and now look at the dialogue in F4, i think i've said everything.
3.Story
The story is better this time (i think) it's not a typical "save the world story" and i'm happy with that.
Unfortunately you can see the plot twists from a mile away.
Combine all of this with a crappy building and managing system and a cool but unnecessary big weapon crafting, i think we have ourselfs an average game full of bugs and bad design choices.
I'il give it a 5 or maximum 6 out of 10.
