>I'd love you to find any first decade TSR book using the term "megadungeon".
A search on Google Trends seems to confirm that the term only started to be used in the 2000s. Picrel. For what it's worth, it's also my recollection: I'm an oldfag and I'm pretty sure the term didn't exist in the Gary (pbuh) days. I've never found "Megadungeon" to be a very useful term.

All of that is true. I wonder though, do you really need to keep replying to you-know-who? I don't think you do.
