Just browsed their website...this looks massive. Might be tempted to go back to D2 just to try this. Looks like it's still in development all these years later.
From what I can tell of the latest release trailers it looks to me like the bulk of Laz's work is still in there despite it having 10 years more dev since I played it, a majority being after Laz handed it over to the community, so I would be cautiously optimistic that it's still the transformative mod it once was!
I'm also tempted to reinstall it!
