Skyrim was rushed just as much as Oblivion that's true, but it feels a bit more justified from a story point of view. In Oblivion you were just an average nobody for the majority of the game, an adventurer, but otherwise, nobody special or irreplaceable. I felt no obligation to continue the main quest after delivering the amulet to Jauffre.
I mean why would he tell this random stranger he knows nothing about where to find the emperors only living heir, I could have just as well been an assassin.
In skyrim, it was kind of justified that you go through with the main quest, since being the 'last dragonborn' meant that only you could 'eat souls'. But it still felt forced, especially whenever I had to interact with Delphine.
I agree with the video though, I still felt that there was room for a bit more criticism in morrowind's case, but the points made were all valid. Morrowind's main quest never felt tedious or forced, if you felt you needed a break, the game anticipated that for you and told you you could, and should have it, which made coming back to it a matter of choice when you felt ready, it made you want to come back it and play it in several sessions. Later games were more of a zerg rush, they just pushed it onto you making it feel as if you needed to do it all in one day, which made the main quests feel very tiresome... at least for me.
