Bethesda hyped this game too much. People expected too much. You can't blame the customers for complaining about Skyrim being an "average" game.
I don't see many people complaining that Skyrim is an average game. Even you used quotes around average, which probably means you think it's subpar. Which leads me to believe you either haven't played many bad games or you have unreasonably high expectations, and I'm a person who doesn't believe there has ever been a 10/10 game ever.
What the situation looks like to me is that people expected an amazing game, got an okay one, and are calling it terrible.
What I don't think is that you can blame Bethesda for the video game hype machine as if they were the only ones who do it. We live in a culture of hype, movies, tv shows, video games, even books. It's not even just done by ad execs but by the fans themselves. How many times have you heard about this awesome amazing game from multiple sources only to find that it isn't what you were led to believe? That's how I felt about Bastion. It's a great game, but I probably would have enjoyed it more if I hadn't heard so many people rave about it.
Skyrim has boring quests compared to pretty much every other game. I'm sick of this "go bring me my socks" kind of quests. Probably, Bethesda was like "Eh, it's too much work to make all these quests. Let's make some crappy misc. quests to increase the number of quests in this game" The idea of having radiant quests was probably based on this.
Everyone is sick of fetch questing yet almost all these types of games have major amounts of them. It is a systemic problem, although Skyrim might be one of the worse offenders.
NPCs are boring because they don't feel alive. When you are walking around, a complete stranger may say things like "Hi there stranger! I have a daughter and I work as a blacksmith and I live over there. Just wanted to let you know!" Geez. Why the fuck are you telling me that? I have never ever seen you in my life. What if I'm a rapist or something? I'm not complaining about frendliness of NPCs. The agressive NPCs don't seem real to me too. They just get pissed at everyhing for no reason. It's like all NPCs have 4-5 personality types.
It's a Bethesda game. Every one of them has been full of bland-ass NPCs. I can't even remember a single character's name from Fallout 3 (except Liam Neesondad) and I beat that game twice, and a surprising number of people have Jiub as a favorite character from Morrowind. Basically all the NPCs suck except the daedra.
If you are doing something other than loving doing it, you are doing it wrong.
This, I agree with completely. Although I believe the people at Bethsoft do genuinely love doing what they do and do try to make great games. It's just that they lack the imagination to try to make something truly great and instead try to refine a formula that seems to make people happy. It's not just Bethesda that's like that.
But is it better or worse then Oblivion?
I'd say Oblivion was better.
Really? Oblivion's dungeons were almost as linear with even less personality, the HP bloat was insane at high levels even on 0% difficulty, and the world was even more bland. Plus, you couldn't catch bees and butterflies. Now
Shivering Isles, on the other hand.
