So I just started this about 3 days ago, having avoided most info other than changes to the core mechanics (like the dialogue system). I reckon I've put about 6 hours in.
I've got to say, it has been tremendously underwhelming so far. I mean, really underwhelming. I love exploring open worlds and Bethesda's take on them in particular, so I'm having a measure of fun anyway, but where I was expecting a generation leap from the last 2 Fallout games I feel like it has almost regressed.
Some quick takes:
-The opening felt super rushed, and 'odd' in tone. So much crazy shit happens in 10 minutes without the time to process it, and the characters don't react realistically (or emotionally) to any of it at all. Just two fades to a 'two weeks later' screen to break up the massive events that were occuring would have improved the entire thing.
-You really feel railroaded into setting up Sanctuary and meeting Dogmeat and the Minutemen at first. I tried to go off the beaten path but struggled finding ammo and supplies, so it felt clear that the game wants to establish you as the big swinging dick of your corner of the map immediately. 'General', lol. Kinda weird to me.
-So then I say 'fuck sanctuary' and run down to the south of the map from from my base and found that the map is way smaller than I was expecting. And there was very little interesting along the way, too. Worst of all I got caught up in a maze of invisible walls at the south of the map that seemed to be placed completely arbitrarily. What I've experienced of the map is far below the standard of Fallout 3 and 4. I haven't seen Diamond City yet, but the wasteland itself seems like a duller retread of Fallout 3.
-The new dialogue system is terrible. End of. The missions so far have been really dull 'clear this area' stuff. No interesting characters whatsoever so far.
-The main character is a boring, milquetoast dude whose presence means I can't really roleplay the game. This guy is so goddamned bland that he might as well not be there... so why the hell is he there? The conversations are nowhere near as well done as the likes of Mass Effect or the Witcher 3 so they should have just left him out.
-Lots of the tutorials were poor, popping up and going away while your attention is focussed elsewhere, on a conversation or battle etc. As a result I had no idea how to build things at the workshop for ages. Once I got the hang of it I have to admit it works better than I expected. But I just don't play a game like this for base-building.
-There are some small but important 'quality-of-life' improvements like how you loot people and containers, and the Borderlands influence with weapons and legendary enemies is well implemented but other than that it plays the exact same.
-There are moments when the game looks great (when the godrays are filtering through an environment) but overall I'm shocked at how shoddy it looks. The texturing is appalling, especially on the front of buildings - the windows are low-res textures, for fuck's sake. The facial animation is laughable. The LOD draw distance is an obvious line on the floor that moves ahead of you as you move. It's just... not good.
I'm sure people have made these points before and been arguing over them since release - I just arrived at this conversation as I just started the game and I know this is already OT2. But right now I'm just shocked at how little Bethesda has improved the game in the 7 years since Fallout 3. I mean, 7 years! In particular, it already seems like a massive step back from New Vegas in writing (plot set-up and characters) map design, dialogue, player options and other things. And at the same time, not nearly the advance I was expecting in graphics, animation, level-of-detail draw distance and lack of bugs (I've encountered plenty already). Even the retention of the songs from Fallout 3 gives the feeling you're playing an expansion as much as any kind of leap forward.
Hopefully this will be a Witcher 3 scenario when I look back and say 'Remember when I didn't like the first 6 hours of this GOTY contender? Boy things changed...'
