Fair enough, Fallout 2 at least did deal with a lot of dark themes that I don't see Bethesda retreading.

In regards to the kids thing, there were ways around it, it was more an annoyance having to buy back stuff that got stolen if one didn't take those precautions and on an evil playthrough could cut the pretense and do it without much consequence besides the perk reputation as the place was a craphole anyway.

The older fallouts needed one to get into the setting to start the ball rolling, it is not a pretty game and would not be above throwing the playable character in difficult situation if they didn't prepare for it but it had a way with its writing that helped one to roleplay once one got to a point where one got established which is an older game paradigm that isn't popular nowadays - building a reputation, and once you have one can start to interact with the world proper.

New Vegas scratches that itch, but isn't completely the same

I suppose it is like playing a interactive book and then falling in love with the writing and systems that represented uncomfortable realities in an interesting way.
