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
I do not believe you have run a modern module if you don't think they let players go wild with solutions. They might include a solution instead of leaving it as an exercise for the DM, but they very much let players approach them however they want.
Anyway, putting random monsters in a room and telling the DM to figure something out is inherently flawed. It's literally incomplete, and has filler encounters. Those are definitely flaws in a prepared adventure. As I've repeatedly said, they wouldn't be flaws in a different type of publication, but we're not discussing that type of publication.
Also, you forgot to defend your actual point. Even if they weren't flaws, how would that make people who don't like that "style" cowards?
I have run Lost mine of Phandelver, several of Dragon of the Icespire Peak adventures, two and half modules from Candlekeep Mysteries, one from Twelve Peculiar Towers, one dms guild adventure, I think this is far from not having run a modern module as you accuse me of.
Ok, then why do you think they don't let players approach issues how they want? You claim you've run them, but you don't have anything to disagree with my argument, and you've still forgotten to defend your original point. Or have you just realised that your arguments are baseless and are just arguing back to try and get the last word in and protect the pride you claim you're willing to put on the line?
