"“Did your office ever consider just confessing error in this case? You've had a bunch of time to think about it. Do you know?" Justice Kagan, at oral arguments.
Some days, I wonder about conversing on the internet. It's like, why bother? I wasn't being particularly mean, or rude, but a claim was made (there was nothing inherently special or different about the design of Tomb of Horrors that made it more deadly) that was ... well, wrong.
And instead of just going, yeah, that was a typo, or a mistake, or thanks for the info, a person doubles down. In arguing, they just directly contradict themselves. It doesn't matter what the point was, just ... LET'S ARGUE, MAN!
Anyway, whether or not you like, or dislike, 1e, or Tomb of Horrors, or whatever doesn't really matter to me. Don't care. You can argue that with someone else. The design was inherently special, because it was designed to avoid monsters and make the players think. It's in the introduction.
To the extent you don't like it, that's your preference. You're welcome to it!
