your question does bring about another question
IF the main quest is taken out and instead you have millions of side quest each with their own unique story in a world like that of Skyrim. Basically that means the world is not in danger, there's people on the wrong side of the law but they've always been there anyways and you travel the world helping people. So the world is in no danger of ending, there's no ancient monster or anything of the sort, you're just a normal guy in a fantasy world making a living. It would be like The Sims meets Skyrim and honestly I wouldn't mind playing something like that
