Well,it's actually something I learned from the people here.It's often said these croppings make the game more appealing to larger groups,so...
It's an echo-chamber effect. It's not true at all.
It's true that things like fast travel makes the game more appealing to the "masses" (not because of any lack of complexity, but because the masses don't have time to walk everywhere) but it's not true that the average gamer can't handle complex ideas. Even Call of Duty players can do math. The only real difference between the more casual target audience and us is that we have enough free time that we can afford to be forgiving, patient, and accepting of a game that doesn't offer a lot of entertainment up front.
There are valid game design reasons, totally unrelated to mass consumer appeal, to cut down on extra skills. Every human being in the world has a limited capacity to track things. Video games have more luxury than tabletop games with vast spreadsheets of data, because the game won't break if the player can't cope with it, but it's still bad game design to put too much pressure on the player to track lots of abstract numbers. You shouldn't add a skill for the sake of adding a skill, you should add it because making that a separate skill has benefits that outweigh the cost in player memory-space. Furthermore, skills are inherently a poor way of adding depth to a game, because all they can do is act as a multiplier - they can't actually enable the player to do anything
new, just old things better. Progression is important, but progression that unlocks new ways of interacting with the world is more interesting than progression that just makes you better at the old ways.
Long story short, "less skills" is a sign for concern, because it's certainly
possible that Bethesda has made a poor design decision. But it doesn't
necessarily mean they've "sold out" and cut skills just so they can laugh maniacally.
