The more I look back on this thread, and blogs out there, and watching this video, the more I am convinced of a common shared behavior. A bunch of people piling on to nitpick every single flaw like it's the worst thing ever to happen in a module, often relying on hyperbole or exaggeration in their attempt to be part of the mob....er...crowd.
I'm not saying the module doesn't have issues. It does. Clearly. But so did a whole bunch of modules of the time. Almost every module was a railroad, and yet N2 is the one being criticized for it. Nearly every module had wonky encounters that didn't make sense. That's how things were largely written in the early 80s. I mean, have you seen any fantasy movie or TV show in the 80s?
But take this video. They are taking a module they heard was awful, and then the DM decided to fudge, exaggerate, and twist what actually was in the module to try to pile on because I guess piling on something is fun? For example, the odds of every party member missing the road are low (12% if you care about the math for a party of 3). And yet, in the video they all did! And the DM failed to mention that the map was an old map and the road has since been completely overgrown since it was made. It didn't have the new road because the map was too old. Context matters. But they spent 5 minutes yelling "how could we miss the ONE road!" And then they encountered 20 baboons which is the maximum (not only rolled a nat 1 on a d20 for encounters, but rolled max number of baboons?). It's like the DM intentionally made everything the worst-case scenario and then patted themselves on the back, saying, "Look how garbage this is!"
That's disingenuous to me. The only real flaws this module has that others didn't were the bad editing and stat blocks. Everything else seems to be selective memory of other modules just to pile onto this one.
