Is it safe to assume all references to AD&D (and the adnd tag) are references to the 1st edition (1e) version of the game?

I can't speak for how everyone will use the term in their questions... :)

But Yes, that is what the is for. To quote the discussion about the d&d tags (from SevenSidedDie's answer):

doesn't need a "1" qualifier. 1) Almost all AD&D 1e questions are relevant to AD&D 2nd edition since it's not significantly different in most regards. 2) If people say "AD&D" without qualifying, they mean 1st edition. 3) If people mean 2nd edition specifically, they invariably say 2nd edition. Hence is a better tag than [adnd1] would be, is more natural, and doesn't cover anything it shouldn't.

Looks like we need to add some definition to the wiki exerpt...

• @Jeff: Thanks! We reworked the dnd* tags recently and apparently some of the wikis/excerpts got lost in the process. – yhw42 Jan 27 '11 at 13:46

AD&D 1e and AD&D 2e are substantially different. Notably, 1e was written during the golden age of the 1970s, solely by E. Gary Gygax; 2e was written in the late 1980s, by David "Zeb" Cook after Gary was ousted from TSR. The differences are myriad (the biggest being Skills). Note that at Dragonsfoot.org, two thriving and separate forums address 1e and 2e.

I strongly suggest that AD&D1e and AD&D2e be separate tags, and the generic AD&D tag be retired/redirected.

• A downvote? Someone isn't familiar with 1e/2e, I suppose. :/ – ExTSR Feb 6 '11 at 20:26
• AD&D2 should definitely have a unique tag. I'm not sure we have many questions directed to it at present though. I'm ambivalent as to whether the other tag should be adnd1 or adnd – Pat Ludwig Feb 7 '11 at 17:58
• On Meta a down vote doesn't indicate that you're incorrect, more disagreement with the conclusion if that makes sense? It's standard voting on SE metas. – Jon Hopkins Feb 8 '11 at 22:04
