While
2nd 1E started it all and had some good stuff with
Leaves from the Inn of the Last Home, 3rd edition dominated with the most detailed resource books that hit all your favorite eras, including but not limited to:
- Age of Mortals 3.5 campaign book + monster manual
- Legends of the Twins (time travel campaign book, go back to Istar at the brink of the Cataclysm, etc., probably my favorite of the bunch)
- War of the Lance (setting book)
- Towers of High Sorcery (great layout for doing the Test)
- Dragons of Krynn (everything you could ever want)
- War of the Lance adventure (3 massive books recreating the DLA Classics of fighting the War)
Personally, I found the AD&D Taladas boxed setting & maps to be a beauty, though it (purposefully) lacks your traditional stuff like the Towers. I ran a trilogy set there using 3 published modules - (DLA1-3,
Dragon Dawn, Knight, & Rest) - which gets about as awesome as you could ever want with dragons + stopping Takhisis + time travel.
Otherwise, there were 3 published modules for Age of Mortals and another 3 promising ones in AD&D (Dragonlance Expansions, DLE1-3), but never played them and can't comment on their quality.
Finally, if you haven't already found it, the fansite
dragonlancenexus.com has always had some great resources.
