And Through a Nightmare, Darkly, and the painting one, and some others, I'm sure.
I happened to love most all of those, and I don't see why anyone would have a problem with them. I mean, if you're in the quest, you should finish it when there's significant pressure to do so. Like being trapped or on a time limit.....
The difference is that, with Through a Nightmare, Darkly and A Brush With Death (and no, I don't remember the names off the top of my head, I'm looking at the UESP.net quest page
) the player is told in advance about being "captive" and the player has to willingly go into the painting or the dream world, unlike the other 2, where all of the sudden the player is captive with no choice other than complete the quest to be able to go back to the open world. And again, I have no problem with that at all, on the contrary.
