This page is being produced as a response to a question on the Mystara mailing list. It is being done off the top of my head as a first pass so I have something quickly. As such, it may be fraught with misspellings and inaccuracies. As always, feedback to me is welcome.

B2 - The Keep on the Borderlands

Plot
Clean out a bunch of caves full of humanoid monsters. The dumbest of dump dungeon crawls.
Setting
Later placed in Karameikos.
Value
Questionable.

B3 - Palace of the Silver Princess

Plot
Dumb dungeon crawl, but playable. Medusa and gargoyle encouters on main line of story may be deadly for B-level characters, though.
Setting
Valley of Haven, later placed on the border between Karameikos and Thyatis. One NPC is of the Thyatis-based Knights of the White Drake who are mentioned as extinct in DotE.
Value
Usable, but old (1983?). Later B modules are better.

B5 - Horror on the Hill

Plot
Dumb dungeon crawl. Where do the living things (and adventurers) in the dungeon get food/light?
Setting
Generic dungeon
Value
Shrug

B7 - Rahasia

Plot
Nice Tracy Hickman dungeon crawl. Strong story line. Playable at level 1 if gargoyle encounter is removed.
Setting
Generic dungeon near elf village.
Value
I started my REAL campaign with this one.

B8 - Journey to the Rock

B9 - Castle Caldwell and Beyond

B10 - Night's Dark Terror

Plot
Strong story. Wilderness adventure with multiple dungeons. All encounter locations related by the ongoing story. Evil magic-user and gang stumble upon treasure of lost civilization but the PCs get there first.
Setting
The first product to refine the Karameikos setting. Kelvin, Rifflian, Dymrak Forest, Threshold, Lost Valley of Hutaaka.
Value
A top five module. Lots of play and lots of xp - raise the party from level 3 to level 5.

B11 - King's Festival

B12 - Queen's Harvest

X2 - Castle Amber

X3 - Curse of Xanathon

X4 - Master of the Desert Nomads [15 Dec 97]

Plot
The party is sent across the Great Waste to spy on the mysterious Master.
Setting
Sind and the Great Waste. An evil monastery.
Story
Unrelated dungeon and wilderness crawls loosely contected by a skeletal story.
Balance
Generally balanced, but an encounter with the Malakaz can end the campaign.
Mechanics
Okay. Uses the 1981 spell progression tables.

X5 - Temple of Death [15 Dec 97]

Plot
Attack on the Master of the Desert Nomads in his fortress. This is the sequel to X4.
Setting
Introduces Hule. The Temple of Death is the fortress.
Story
Dungeon and wilderness crawls are tied together fairly well. Requires some simple-minded willing suspension of disbelief.
Balance
Okay until the fortress is breached. The Master is a killer monster for a 10th level party like the adventure is supposed to be written for. Even without him, the fortress could be DM'ed to wipe out the PCs. But it's not Castle Ravenloft :)
Mechanics
Okay. Uses 1981 spell progression tables.

X7 - War Rafts of Kron

X8 - Drums on Fire Mountain

Plot
Strong story. Wilderness/dungeon crawl. All locations related by story. Evil magic-user (with a twist) using orcs (and other friends) as pirate minions. Lost civilization.
Setting
Teki-nura-ria, an island placed SE of Thyatis where the adventure starts.
Value
Lots of treasure and xp. Good story.

X10 - Red Arrow, Black Shield

Plot
Strong story. Played on three levels: RPG, BattleSystem, and War Machine. (I wrote a program to play the War Machine level.) Master of Desert Nomads attacks Darokin. PCs go on diplomatic missions across the continent to build an anti-Master alliance. A top-five module.
Setting
All the countries of the Gazetteer series.
Value
Lots of treasure and xp. Strong story. Unique, three-level module.

X11 - Saga of the Shadow Lord

Plot
Strong story. Wilderness and multiple dungeons connected by storyline. Foil the evil wizard/undead who is trying to use his power to make Denegoth a base for futher conquests.
Setting
Wendar and Denegoth (north of Glantri).
Value
Good story. Playable. Lots of treasure and xp.

CM2 - Death's Ride

Plot
Strong story. Major attack of undead launched by Magic-user, Cleric, and dragon. The undead overwhelm one of the Norwold baronies.
Setting
The best of the Norwold modules.
Value
Good, playable story. Unique and heavy use of Companion level undead monsters.

CM5 - Mystery of the Snow Pearls

A unique product. This one player adventure is a do it alone. The module book is read by holding the included (in the original) red cellophane paper of the pages which have been "encryted" with red ink. I don't know anything else about since even though I have a copy, I've never played it.

CM6 - Where Chaos Reigns [17 Dec 97]

Plot
Party is transported to another world to thwart the attemtps of the Oards to rewrite history.
Setting
Another (not Known) world.

CM7 - Tree of Life [17 Dec 97]

Plot
Alfheim elves travel to Sylvan Realm to rescue original Tree of Life from evil wizard.
Setting
Alfheim, Rainbow Bridge, and Sylvan Realm.
Story
Strong
Balance
Difficult at times.
Mechanics
Adventure for elves and one human druid. A pregenerated party is provided.

CM8 - The Endless Stair [28 May 97]

Plot
Investigation of the death of a man brought to the inn where the party is staying leads to a wizard's tomb.
Setting
Glantri is suggested. In my campaign I set it in Darokin because the module does not deal with Glantri's ban on clerics.
Story
Strong
Balance
Playable, but expect some to have to do some Raising. Low on xp. Treasures of value only to Magic-users.
Mechanics
Weak. Ed Greenwood plays fast and loose. The module was probably written for AD&D anyway.

CM9 - Legacy of Blood [17 Dec 97]

Plot
Take over troubled dominion and save it from the curses with which it is afflicted.
Setting
Darokin
Story
Strong
Balance
Good
Mechanics
Good

M3 - Talons of Night

Plot
Good, complex story. Evil immortals try to destroy Thyatis and Alphatia by kidnapping Thincol and Eriadna from peace conference and taking them to an extra-planar undead Isle of Dawn.
Setting
Only module set on Isle of Dawn. Lots of emphasis on Thothia.
Value
Good, playable, HIGH-level story.
