I'm following this mod and it's development from the very beginning.
The team created basically something bigger then just a mod for the original game. It feels content wise more then a real addon.
It fills the gaps & longed content missing (yet) in the vanilla game with additional (side) questlines that have been placed carefully alongside the vanilla story.
The content itself fits pretty well in the 'BB-verse' for the most part. Many common desires from the community are considered, always with even more content in sight, as the vanilla game also makes it's progress.
The writing as well as the renders are really high quality for the most part, IMHO some even better then vanilla renders (and writing/spelling for sure).
The only downside for me personally is the concession to lock some of this content behind RNG mechanics or rather combine the 'hidden content' with these RNG mechanics.
With a bad RNG streak, you might have to play several in game weeks repetitively for some certain scenes or events, which doesn't trade of fairly, considering the 'time investment' vs.. a few renders a few sentences as reward.
Some may like that challenge, some might don't bother much and some may don't like it at all.
I personally stopped playing at some point because of it (v3.0).
Each to their own.
However, if you are not completely bothered by that, you basically -have to- give that mod a try.
The general level of quality and detail might reimburse the RNG 'flaw' greatly.
