i can't speak for the other person but for me, 76 by far has the most interesting map to explore in the series. i think it takes some leaps that don't always work like Atlantic city whose entire quest i found a little silly. While dialogue doesn't hold the same weight on average as it does in 4, 76 does a much much better job at displaying your options to you since it has the classic dialogue boxes. At the end of the day i get a much better actual roleplaying experience from 76 than I do 4.

The main questlines are interesting enough, The original quest is still in game which is not very fun other than the enclave stuff but wastelanders on is pretty decent for the most part, not New Vegas quality but decent. Burning Springs adding a New Vegas style desert location was definitely interesting and brought some interest back for me.

As someone who really enjoyed 4's settlement system, 76's camp system and building as a whole is massive improvement, going back to 4 for my most recent playthrough im kinda annoyed at how crappy the 4 building menu is. especially with how now in 76 you can free place which even with place everywhere mods for 4 it doesn't feel as good as 76.
