so.... I'll just explain my experience. Nothing but facts as I've experienced the game. Use it as you see fit in making your decisions.
I've only experienced 2 bugs. 1 is strictly cosmetic. With an NVidia gfx card and the latest drivers, my face texture gets messed up on occasion. I can simply quicksave and reload to fix it, but it comes back randomly on other reloads. This is only an issue when talking to others in 3rd person. So its not only cosmetic, but also manually fixable. Would love to see this fixed (I have submitted a detailed bug report since beta 3 patch did not fix it).
The other bug is more frustrating, but it also has a work around. If you are working on the settlement happiness achievement (which many don't care about), you can't leave your settlement until done as the people will turn angry as soon as you leave. They already applied a minor fix to this issue, but it didn't solve the problem 100% (although it did help). The simple work around is to wait until you really want to work on your settlement and do it all at once. As long as you don't leave town, the happiness meter works fine.
At level 50 with 155 hours of gametime under my belt, I've yet to see another bug.
The game does a poor job of communicating with the player (you). For instance, the people complaining about the quests simply don't know they are performing radial and endlessly repeating quests. Those quests are good as they provide a quick means to XP, resources, and a great way to boost your companion relationships. However, they aren't mandatory, and people should understand that they are intended only for people wanting to grind out certain things. Once you know which quests are radial/repeating, the game isn't nearly as monotonous as most are making it out. Another instance is hiding your weapon. Even the game hints suggest putting your weapon away... but I had to google how to do that. Its not a configurable key in the settings, you have to hold down another action key. There were multiple issues that I THOUGHT were bugs, but after researching, they turned out to be poorly communicated issues that were working as intended (and fully made sense once I understand what was supposed to be happening). Yet another example is in the homesteads. The game tells you that building a store will generate revenue. Thats it. How much? how do I get it? how often? no more info to be found in game. I finally found out that caps were input into the workbench and I had to withdraw from that. For quite a while I thought the bug existed where I wasn't getting paid, but it was simply a communication issue as to how and where I was getting paid.
The focal point of the game is free roaming exploration. If you did not like Skyrim, you probably won't like this. But, unlike many (reportedly), I also didn't experience many bugs with Skyrim. I'm a big fan of looting, hoarding, breaking/entering/lockpicking/hacking, etc. I love the bobbleheads, skill magazines, lunchboxes, etc. scattered all over the world. Snooping through folks' email, stealing their ink pens, and then dashing out to the next place is good fun in my book. This game is full of that. And some of the non-main-arc quests are very well written and voiced. The companions you can choose from are also very well written and voiced, but be prepared to send them packing as they constantly bump into and magically manage to step right in front of you just as you clicking that item they decided to block. grrrrrrrrrr. Still.... Piper is a must have companion. I also like dog and the detective.
The item sorting is atrocious. I've seen a few mods but still nothing solves the overall issue. Lots and lots of scrolling involved here. How silly to not have a simple search function. Same goes for the map.
I hope this is the last game I buy before the DLC is released. I was very upset to realize that the PIP boy edition came with a flyer for the DLC and not the DLC itself. So rather than make that mistake again, I'll set out to only purchase after the definitive version is released. This will also leave room for bug fixes, etc.
If you enjoyed Skyrim or Fallout 3, I would highly recommend this game. If you hate Bethesda no matter what they do, or don't like the standard quests that accompany most RPG games, I would strongly encourage you to wait this one out. Otherwise, its already worth the overpriced version I paid for to get the game. I have no regrets and am looking forward to the first DLC announcements. But I have learned my lesson. Fallout 5, Dishonored 2, Doom, etc... Doesn't matter the title, I owe it to myself to wait out the DLC cycle to see what direction the game goes before I will buy the original launch title.
Hope that helps folks genuinely looking to make a purchase decision.
