My review of the game so far:
I think they've done a superb job overall. The world in terms of interesting exploration and things to do/find is top-notch. I preferred exploration in FO3 over NV, and this game has delivered in terms of the exploration I expect from Bethesda - with the bonus that you can make your way around above ground even in the middle of Boston, so it feels more open (if you recall, FO3 above ground areas in the centre of DC were cells cut off by insurmountable rubble and accessed via subway tunnels - good for performance, but a little claustrophobic).
A plethora of weapon and armour choices and crafting options for modding gear means that you can tailor all sorts of things to your build, there's nothing that I have found so far that is a clear 'the best weapon in the game' regardless of build or anything like that.
Love the settlement building aspect to it, to me it adds so much to the game and I really enjoy it. For those who don't want to do it the good news is it's entirely optional. I wouldn't mind an inbuilt free camera view for building though, I know that sort of thing can be toggled in the command console on PC, but when building in settlements it would be good to be able to zoom out a bit further (this could be made to seem immersive by having something like a 'theodolite' interactable attached to the workbench that you can activate in order to enter a zoomed out free-camera building mode). Settlement and settler management could do with a bit of tweaking to make it easier to keep track of who has what job within a settlement, and to highlight placement of existing items such as defensive structures, crops, water pumps.
Questing - I've always liked the idea of Radiant quests (in Skyrim and here too), but in reality it sends you back to the same few places too frequently. A worthwhile addition on top of a full roster of individually designed and well thought out quests? A way of getting you interested in visiting a location you may not have come across yet? Absolutely fine. I feel there is a little too much 'Radiant' going on here though. The fact that some of them are on a timer where you will auto-fail if you don't complete them quickly enough makes me feel as though I am constantly rushing to get inconsequential things done - it's busywork, and tbh it is starting to frustrate me constantly being hammered with quests.
The way I would prefer it to be done: don't auto-allocate another quest as I turn in the previous one, and don't have a potential companion giving out quests so that it's difficult to tell him to wait without picking up a timed quest. In fact don't have them on a timer. And make me have to ASK for work before being given a new radiant quest. I have a world to explore, don't pressurise me into rescuing kidnapped people within 4 game days or putting up an atmospheric beacon asap when I want to go and spend some time doing settlement building or modding my gear or just wandering around to see what is in that corner of the map I haven't explored yet. This is actually my main problem with the game - I mean I love it and am still giving it 9/10, but I do feel a bit trapped in an endless round of time-sensitive questing, it would be good if I could easily decide to take a break from it without quests auto-failing because I didn't get around to doing them quick enough.
Not keen on the radial dialogue choices, I prefer to see what my character is going to say, it's not always obvious. Also you don't always have the option to explore all dialogue (such as if you pick the persuade option, you can't then go back and ask for more information about the location). Preferred FO3/NV dialogue selection methods.
VATS - make it a settings option whether entering VATS pauses the game for 100% turn-based combat, or just slows it down (or make it tied to difficulty level) - there are easy ways to keep everyone happy, and this would be one.
Overall, an excellent game though.
