On replay, the most dreadful part of the game is right before the point of no return...
Once you've played the game once, you know when that little messag will appear, the one that tells you that once you proceed, you'd never be able to go back. No more exploring, no more questing, no more going to the marketplace and talking to people, and enjoying the sights.
And everything you see around you will be gone and everyone would be too. Our character doesn't know that of course, they don't feel that sense of foreboding but we, the players, do. And walking around Ark or taking a trip somewhere else in Enderal, you just don't want to go and finish the game, you don't want all of this to be gone.
I found myself wandering aimlessly around, buying stuff from merchants I won't ever get to use, visiting the taverns, dancing to the bard music (with the help of a mod of course). I feel like the game designers knew this was the feeling this part of the game would make you feel on replay. It's why Jespar's final companion quest kind of contributes to that feeling too. Having you visit the Dancing Nomad one last time, listen to musicians you'll never hear again. It's kind of dreadful in its own way.
I guess those are the perks of a game that ends on such a sad note unlike others where you can just keep questing after you save the world.
