It occurs to me that, perhaps, 1e is better structured for dungeon crawls than 3rd or later editions. I'm not saying that's good or bad - but it's certainly a thing.
To elaborate: 1e *(as I recall) is about discovery, strategy, and risk. Risk as in pushing your luck, and strategy as in managing long-term resources - but mostly discovery - what's in there, what is that thing, and who is my character?
On the other hand, 4e is about epicness, tactics, and mastery. You mitigate risks by mastering the system, the resource you pay the most attention to is actions, and it's not about learning who/where/what you are, but seeing how far you can go.
5e can do either, of course - but it doesn't do them as well as a more focused system.
