I play it on the Xbox (still really try hard to play it... though some critical bug, be it a system crash, corrupted saves, or a quest-breaking bug, will always inevitably appear within a few hours of playing it forcing me to quit for another few months).
I played NV, on my XBox, last month. I bought a used copy because I read good things about the game on the forum, But, I was nervous because I'd also read numerous "bug" comments.
I finished the game without having any major issue that I can remember. This could be due to the particular path I chose throughout the game. At any rate ... I didn't run into anything "within a few hours" of starting the game that was in any way a game or quest "breaker".
But "Skyrim bugginess vs. NV bugginess" isn't what the thread is about, so I'll just get back to the OP.
And I agree that there is no reason that the a TES game couldn't include logic re: "If you wear a certain faction armor it affects some aspects of the game.".
Though in terms of Skyrim, this might only be pertinent for the Legion - Stormcloak "disagreement."
You could expand it to include Nightingale, DB, and Forsworn so-called armor.
However in these cases, and if the game followed any sort of logic, presumably everyone outside of your own faction would attack you, assuming people actually recognized the DB or Nightingal armor for what it was.
And this might not work for the crowd who wants the ability to "do anything" however, don't seem keen on living with the logical outcomes of certain "do anything" scenarios.
For example, some might want to spend the game running around in DB armor however, the logical outcome of this would be for just about everyone, e.g., town guard, legionarre, etc., ... to attack you on sight.
Which might throw your game off a bit and prevent you from getting all "achievements", guild master status, etc. as quickly as possible or, in some cases, at all.
And if you chose to be a DB member, presumably entry to other guilds might be barred to you.
Which would seem logical given that for everything else in Skyrim, everyone seems to know what you've done, e.g., steal, even when there are no witnesses in the vicinity to see you do it.
So on this basis, obviously everyone would know you've joined the DB immediately after you've done so and perhaps might not be keen on you joining their guild ... much less make you guild master.
But then, you might come here and carry on about how the game "stopped you" from doing something, etc.
So the larger issue is that some people want to "do anything" but don't necesarrily want to deal with what might seem to most to be the logical outcome/consequence of that choice.
And to reduce the chance of a player being "upset" by some sort of unforseen consequence to a decision they've made, Skyrim has been created as pretty much a logic-free zone.
And I mean "logic" that is, or should be, appropriate within the game world.
And in my view, this is ... as Longknife and others have more or less said ... a conscious decision by Beth to focus the game on the "I want to do everything and get every "achievement" as quickly as possible" player who will run through the game once and then never visit ... except perhaps for the occasional DLC ... Nirn again.
And maybe that's a good business decision ... at least in the relative short-term ... on Beth's part.
And the fact is that if you don't have to really care much about choice/consequence type things or worry about anything appearing "logical" ... e.g., why not let me stroll in off the street to Ulfric's palace in full legion armor and have him ramble on about about his stategy and have nobody pay me the slightest heed at all ... it's likely much easier to build the game and just focus on the eye candy stuff.
And if you want to be a bit cynical about it, this works well because it keeps players and reviewers going "ooh, ah beautiful" for a period of time after the intial release ... so you get great reviews and if these happen to change a bit after a bit of time goes by and people have played more and start to notice a few "not so beautiful" things, it doesn't really matter because the games have already been sold.
Just throw in a few "flying vampire lord" type gimmicks every once in awhile and everybody is happy

.
I'd suggest that the real "issues" that result in these threads popping up is that some folks are still expecting a TES game to deliver on their RPG needs ... and I am in no way saying they are wrong in this regard ... rather than just accepting that TES games are now an action/hiking simulator game with a few vestiges of fantasy genre RPG elements left in to dress it up and just leave things at that.
