I can also see it from your perspective, though I have to ask; When you classify something as good or bad, what is the credibility behind that classification? Is it general public opinion or your own opinion? And what has influenced those opinions. What truly makes something good or bad? If you never played video games and all you heard was the public opinion that Skyrim was bad, would that become the accepted classification of the game, and would you base further games against it in such a way?
It's generally the opinion of accepted critics--not public nor my own, though in your defense and to destroy my own argument because I believe it fervently, to paraphrase Candid "If you think it's bad it is bad" (This coming from the section in which Candid is in iirc Italy and examining the Library owned by a nobleman which contains none of the great classics like the Illiad; I must say however that I didn't read this section critically enough to ascertain if this is Voltaire's own opinion or one he was lampooning). So accepted critics (scholars, teachers, etc.) and myself are the only people I really listen to when it comes to books (Because I'm high and mighty, my opinion on things is counted equal to the opinions of persons who hold doctorates on the subject).
Generally speaking, though, literature contains plausible pacing up to the climix of the story--the lack thereof is what destroys Skyrim's writing. One second I'm Dr. Dirkles, the new initiate of the College of Winterhold, the next second I'm assumed to be Lord Dirklemerlin, when in my head I'm still just a lowly associate. What's worse is the implausible conclusion--"Oh, so and so said you should be Archmage and despite being the seniormost staffmember and the guy most likely to actually run the school, I agree with them." In fact, the ending could simply be fixed by the Psijic's not saying you should be Archmage, but rather Tolfdir and the other teachers gathering, discussing who should lead, choosing you, and having a little pomp and circumstance. In fact, just a little pomp would make the ending infinitely more rewarding (including Mr. Hoshtilities saying "See, I knew you had the aptitude to be a great mage!" rather than his usual crap).
I usually base my decision on whether or not a piece of literature or writing is good or not on the underlying message, its structure, the author's grasp of the language, and other misc. things drilled in to you by English courses. Critical reading skills are what let you know if a piece of writing is good or bad--but not whether or not you enjoy it.
As to the last, I couldn't say because I wouldn't have played it. My response would be "I've heard bad things about it."
