You are presenting a completely unrealistic scenario so your post is obsolete. Features were streamlined in Skyrim and features were added. I would agree that some features were simplified to an extent that detracted from the game, but I do not think the game is degenerate by any stretch of the imagination.
Actually, I am presenting a somewhat exaggerated scenario to illustrate the point. To me the addition of quest markers, map markers and POI markers on the compass in Oblivion were pretty much the equivalent of the above scenario. It COMPLETELY destroyed the ability and enjoyment of exploration and it destroyed any self-rewarding feeling of actually finding the place on your own. At least in Skyrim, I was able to turn off the compass and markers before I played the game.
This particular 'addition' was done for two reasons.
1) The addition of voice content for every character, which prohibited lengthy directions given by NPCs. This was done because because so many people complained about having so much to READ in Morrowind.
2) Even with directions given by NPCs in Morrowind, many people STILL complained about getting lost or not being able to find anything.
Bethesdas response was to completely eliminate the possibility that SOME people might get confused, lost, or generally disgruntled with the game because of their inability to follow simple directions. Likely in many cases because they failed to actually read the text they were given and simply skipped it.
That is the most classic example I can think of for 'dumbing down'. The game mechanics were changed to cater to a group of people because reading for comprehension posed to much of a challenge.
