I was listening to the Nerd Poker podcast, and they were talking about switching back to D&D 2nd Edition from 4th, and it reminded me that in spite of buying all the 2E books as a kid I never actually played it as written - I just skimmed the books incessantly and uses them as inspiration for a weird mishmash of house-rules and freeform play. (I wrote a longer account of this here: http://www.story-games.com/forums/discussion/comment/371706#Comment_371706
I regret nothing, but I realized that, to this day, I basically know nothing about how 2E works or what it's like to play. It seems like sort of the lost edition - lots of people play Basic, AD&D, and 3.5, but not so many still play 2E. So, what was/is good about it? What did it do better than other editions? What kinds of adventures did you have with it?
