People are so quick to complain about features that are missing from other games instead of praising all the great things you can do in skyrim.
I don't think people are "quick" to complain and I didn't see the OP as a "complaint" at all.
I do find many people "quick" to jump in and defend Skyrim even when no real complaint or outright negative and unjustified (in most people's eyes) comment has been made, i.e., OP offers their own observations in the sincere, and likely naive, hope that something they find a bit "weak" in the game might be improved and gets jumped all over for doing so.
In my view, the real issue isn't that Skyrim doesn't let you disguise yourself in the manner OP mentioned.
The real issue is, in my opinion, that in Skyrim, it doesn't matter what you do, i.e., there's no need to disguise yourself because nobody cares what you're wearing or, for the most part, what your actions/decisions are.
Skyrim is, as I previously mentioned, pretty much a "logic-free" zone.
And many people have come at this "real issue" from different angles, e.g., "no real or consistent recognition", "no logic in the way NPCs react to you", etc.
But it all boils down to the same cause which is keep things "logic-free" so the players who wants to do everything and obtain every achievement possible on their first ... and perhaps only ... play-through is able to do so.
And that's not just an "oversight" on Beth's part.
And isn't due to "they didn't have enough time" because some of it is exactly the same, or worse, than Oblivion.
I'm lucky because I just started playing TES ... with Oblivion ... so I don't have the same "investment" in the series that some long-time fans do ... so stuff that might be quite upsetting for them , based on their support of the series through the years, may just be mildly annoying for me.
It's easier for me to just accept TES as a light action/hiking simulator "no real thought required" game and get fun out of it on that basis ... and avoid parts that on a previous playthrough I found to be annying, outright stupid or demonstrative of a "don't care" attitude on the developer's part.
In my opinion, Beth has created a beautiful and very detailed world in which to adventure around.
But oher than that, there isn't much I'd find particularly praiseworthy or more than mediocre at best ... but, that's just my opinion and I certainly wouldn't criticize anyone who felt differently.
And if the mediocrity directly relates to more sales for Beth, well that's just good business ... or at least may appear to be in the relatively short term view.
