B&W is still good, it just couldn't reach the very high bar set by HoS.
I think part of the problem is that assuming they are played and completed in the intended order (TW3 > HoS > B&W), then by the mid-end of B&W sheer gaming fatigue is likely setting in (what is the playtime by then? 150-200 hours?).
Anyway, B&W has its moments too. The fairytale land comes to mind. I also enjoyed assaulting the Flaming Rose camps and bandit strongholds. Bruxae and Alp fights are good too.
In my save it says cca 61 Hours that's with the main game completed and first quests in both expansions. Seems a bit too short, I guess I should have taken my time a bit more.
The problem...well it's not really a problem, but the trouble with the game is that it's so goddamn huge and while every single thing I found interested me, I never seemed to progress anywhere until I dove deep into one questline but by then I outlevel other stuff and when I want to switch to some other activity, I get discouraged by a new setup, new quest instructions, new bestiary and journal readings before the meat of the activity, be it quest or crafting or whatever, really starts. This makes it tiresome for me to be exploring the breadth of the game. I mean, I can't fault the game for that, I think it's a great strength that it's so big and almost everything in it is great, I just wish maybe the leveling system wasn't so insanely retarded so that I do get some rewards for finishing lower level stuff because it's all interesting.
I usually play in focused sessions, today I spent 2-3 hours crafting ursine armor and doing some shopping, lol and I'm not even finished. This is completely insane, that's half the time it takes you to finish D00M 2016.
Basically, the game requires an enormous amount of time to enjoy it as fully as you can (and I do mean enjoy, not "tick all the quest boxes because I'm bored") but by then you kinda need to do something else, play something else for a bit because, at least me, I can't spend a full month playing the same game every day, especially one as slow going and erratic as this. Of course I could rephrase it to say "this game provides hundreds of hours of interesting content" but it's not the same as playing retarded Skyrim where you follow your retard arrow and click on things to die and put buckets on horses heads. If you want to get the experience from TW3, you need to read most of the stuff presented to you, pay attention to the dialogues, explore with your EYES not with your fucking quest compass (at least that's what I do, again I strongly urge you guys to remove the minimap and markers and everything else!!).
My friend played TW3 in small sessions for a year to get the full proper experience, without playing anything else inbetween. Jesus, I can't do that.
