It's hardly a rationalization, it's a prioritization. Games have a finite resource pool they can draw upon. Technical resources, Monetary resources, and time. The perfect game would never be released, it comes down to making what is felt to be the best compromise possible given the restrictions. That's not even counting that a lot of things "Fringe" Groups like, a larger majority absolutely hate (Lack of Fast Travel, or quest markers for example). Frankly, your argument comes off as quite selfish, and patently ludicrous. It could be TL;DR'd to "Pander to me, not someone else".
And mind you, I say this as a person who agrees that Elder Scrolls is evolving in a way I'm not particularly fond of a great deal of the time.
Honestly, to say that Elder Scrolls isn't Elder Scrolls anymore is to completely miss the point of the entire series. Each game has been so vastly different, their one common thread is creating as open ended an experience as possible. When you consider the contemporary market, they've never done anything but succeeded beyond all reasonable expectations.
Anyone can think Skyrim, Oblivion, Morrowind, Daggerfall or Arena are better or worse than whatever game they want, but to mire any argument in such ignorance and selfishness really invalidates their position in a discussion.
First of all, can you explain how pandering to this "someone else" is somehow better than me? Can you even divine a reason...do you even know me well enough to say that it would be any better or worse? For starters, I'll say right here that I do not fall into the "immersion" or "no fast travel, no markers" camp. As the consumer, they are trying to attain my money, and other people's money, so they are clearly going to have to pander to someone. What makes this "someone else" so much better, so much more "worthy"?
The hype surrounding the game pre-release was at a very high point, I figure that regardless of how the game actually turned out, it would have been successful. Indeed, it comes off as very mediocre to me, it's a "good" game, but not a great one, and certainly not what it was hyped up to be, nor do I feel it deserving of all the accolades it has apparently swept up in the midst of the hype.
And second of all, drop that argument. Really. I already said I don't care that it is a "poor TES" game to some people.
Despite its claims at freedom, it fails to even truly deliver in that respect beyond being able to walk wherever you want. Your character is largely rail-roaded, the world is soul-less and feels artificial outside of its beauty, the stories are at times nonsensical, others poorly written and acted, the rpg statistics gone, mechanics as broken and exploitable as ever, and the combat lackluster, and archaic. The game simply isn't greater than the sum of its parts..its actually less, as it is clear they did not treat every part of the game with the same care, despite the reliance upon how they interact to deliver the whole game experience.
Like I've said, it is a game with an identity crisis, which hurts itself by lacking a truly focused vision by trying to be too many things, some of which it never was and never needed to be.
