B4: The Lost City is a classic module for D&D. At one point it (in)famously stops giving full description of the rooms but instead lists monsters in each area and tells the DM to figure out why they're here themselves. Once the reprint will show up in new anthology, I'm sure people who complain online whenever WotC uses "ruling not rules" or "DM decides" or "these parts were left for the DM to fill in" in their design (and then continues buying WotC books to keep bitching and doesn't touch 3rd party or other games for some reason) is going to be normal about it. /s
Personally, I'm not. The last WotC product I bought was Fizban, I think. At that point they had already started disappointing with the quality of their content, and it only got worse and worse with even removing huge amounts of content from already-purchased books in digital form. I wasn't playing much during the pandemic, but when I finally picked it up again last year, I decided to switch to Pathfinder 2e. Both a much better product and a much better company producing said product.
