It's fun! There are a few mechanical things that are just better in dark days (people talk shit about pockets, but it's the best thing that's been added in years) and the mods hadn't moved over when i played it last, but it's generally a better experience.

Edit after looking for the newest update to BN: holy shit the mods. The mods have moved over, they are in a better place, they are more extensive, there is no reason to ever go back now.
