Nightfall:

Those Meta posts are really driving behavior here, aren't they?
If it's a complaint about attitudes in general, I half agree philosophically. The whole idea of characters growing to become the mightiest heroes of the land, or gods, or whathaveyou and completely remolding the campaign setting to their image really turns me off, and to be fair, it might very well be based on some really lousy games I had in junior high.
At the same time, DMs who can't abide any change to their work of art, static campaign setting turn me off too -- so I'm kinda on the edge of this one philosophically.
In practice, the complaint comes off sounding a bit whiny though -- "I want to kill a Night King and take his stuff -- but the DM won't let me." True, it may not have been meant like that at all, but it comes off that way anyhow.
