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
you know why gamefreak games suck (to use an unrelated example)? People that will just accept whatever garbage is given to them without complaint instead of having standards. If I'm buying an adventure path i expect it to be complete. Hell that applies to dnd broadly as well, awful, incomplete, overpriced game that it is.
