Red Hand of Doom seems hands down a much higher quality than everything else. Anyone have an idea of why it turned out so much better?
To be honest, I consider RHoD to be over-rated. It's a very very good adventure, but it has some very significant weaknesses. (Notably, it has five chapters that you must tackle in order, at each chapter has a fairly short sequence of encounters that you have to tackle pretty much in order. There's actually not a lot of scope for diversion from the pre-written plot there.)
But it scores extremely well for three big reasons: firstly, it was the first major WotC adventure book published for some years, and at a time when people were calling out for more adventures. Secondly, in comparison to both the adventures that preceded and that followed it, it is markedly better. And thirdly, despite being a railroad, it does present a decent selection of opponents, and presents a classic plot well - it's good at what it does.
Or, do folks consider it to be not quite big enough to be a proper adventure path? I'm interested in what would qualify as an adventure path. The whole Against the Giants line of modules seems to be nearly there, although, it spans level 8-14, and not 1-14 or 1-20 as do other adventure paths.
Technically, an Adventure Path should be a series of adventures that provides a complete campaign. So GDQ1-7 would be the earliest TSR example, followed by Dragonlance, then WotC did the 3e path, Dungeon did Shackled City, Age of Worms, and Savage Tide, there was the 4e set of nine adventures, and of course Paizo's Pathfinder adventures.
"Red Hand of Doom" would therefore be excluded for being too short - covering levels 5-10 it's more likely to be a part of a campaign rather than the whole. And, of course, it's also only a single adventure.
(Arguably, this same definition also excludes "Princes of the Apocalypse" and "Out of the Abyss" - are these one big adventure, or several collected into a single volume.)
Worth noting, of course, that that's just
my definition, and is neither universal nor perfect.
