As a kid, I never owned any Dragon magazines, I'm not even sure if I even knew of it until around 1990, and even then, with the budget issues I had, I probably wouldn't have seen the use it buying it anyways. I was lucky enough to buy a few dungeon magazines though, not many but a few. I say lucky because, wow, some of those submissions were very well written. Two of my favorites included a library where the rooms shift around in issue 29, and an Underdark adventure involving a massive multidimensional alien in issue 24.
I think one of the things that would impress me the most about these adventures, was that many times the designers were either high schoolers, or college kids close in age to myself. I would read these mini-modules with a mixture of admiration and envy that such quality products could be written by such young people.
At first I thought is was strange that I rarely saw anything written about them in the old school blogs, but I realized that dungeon magazine was mostly a 2e (and beyond) resource. Still though, to me, converting between 2e and 1e (or B/X for that matter) was no big deal.
I remember reading on JM's Grognardia about the lack of truly memorable 2e modules, and some-one had quite rightly pointed out that although the offically released 2e modules were mostly forgettable, Dungeon magazine was releasing some great material at the time (a sentiment I would have to agree with from what little I had read in the magazines).
The thing is though, that although the few I had were impressive as reads, I never had a chance to actually use any of them in play (only because by that time I was mostly a player, and never a DM). I guess this leaves me wondering how playable they would have been. I'd hate to here that they were like most 2e materials, interesting to read but impossible to use in play.
