D&D General Iconic and Best Adventures in each Edition

[Eyes of Nine]

I think megadungeons are adventures that carry a lot of weight in the game, even if they’re not to everyone’s taste. There are many out there but I’d give my vote to Rappan Athuk as the best of them from 3e onwards.

I hadn't put any 3P items on my list, but if we are talking megadungeons, have to prop up Arden Vul - what a banger! Playing in it now, looking forward to reading it after this campaign ends...

I’d never heard of Arden Vul till your post. Just had a look at it and Wow!
Looks awesome.
