How many relevant supplements did AOG do?
Well, that mostly depends on what one considers relevant.
Their variants books are pretty much useless for RPG-ers, cause they contain mostly rule additions and new ship versions (they can be useful for hardcore gamers, who want to surprise their players with an variant though, but are low priority for most RPG guys). "Ships of the Fleet" is just that - a collection of ship BG and control sheets; nice to have a bit of BG for ship classes, but not really neccessary for roleplaing... The "Tactics Guide" is also rather game specific... everything else though contains at least enough BG fluff to make these races come alive in a campaign.
The "
Rules Compendium" has all the basic B5W rules, but also some BG info for the major governments, and the AoG star map (agreed, the new one is now "in effect", but still...).
"
Wars of the Earth Alliance" had some info on the EA/Minbari war and the EA civil war, but is almost impossible to find, and not even correct anymore, as most new Minbari ships were redesigned after it's release (they look a LOT better now - check the minis!)
"
The Dilgar Invasion" and "
Showdowns-4" covers the dilgar war, with a complete history of how it went, descriptions of the major races involved not already mentioned elsewhere (Dilgar, Alacan, Balosians, Descarii, Markab, Llort) and of course the ships of these days.
"
The Coming of Shadows" is old and hard to find, but covers the Shadows and the Vorlons, and their conflict withing B5 time, while "
Wars of the Ancients" gives you tons on BG about the other first ones, and what went on when the Vorlons were still young.
"
Militaries of the League..." is just that - the first (hard to find) one covers Abbai, Brakiri, Drazi, Gaim, Pak'ma'ra and Vree, while the second has Cascor, Grome, Hurr, Hyach, Ipsha, Kor-Lyans & Torata. "
Showdowns-2" has a bit more stuff for the MotL-1 races, while "
SD-7" a lot more for MotL-2 races and a small section for the Yolu too.
"
Raiders, Pirates & Privateers" covers the Llort, Raiders and their oppoennts - police forces of several races as well as the human "Belt Alliance". There was a second one under production, released as download in their final days, which covers more non-human raiders & freighters, as well as the Deneth.
"
Wars of the Centauri Republic" and "
SD-8" take a look at the "Lion of the Galaxy" during their prime, when their empire spanned as much space as the whole "B5 map" and they were about to clash with their first truly serious opponent, the Orieni Empire. Hard to get nowadays, even though it was one of their latter ones.
"
Showdowns-5" covers the Narn/Centauri war (actually re-covers it, as there was the 1st Edition "War of Retribution" which is and has been out of print for a while... SD-5 may be better anyway, even though it doesn't give you all those nice drawings), and the Corillani who were caught up in it.
"
SD-3" does a peek at new crusade-era EA ships, the Streib, a little war between raiders and Minbari client races and one of the Ancients, the Kirishiac Lords, but not enough of any of those to really warrant getting it for a common RPG guy (well... except maybe the Kirishiac...).
Finally, "
SD-6" covers some of the minor wars within the League - the Descarii/Gaim conflict as well as Drazi vs. Brakiri and Balosian skirmishes.
As for getting them... ask Agent-1, he's privately selling lots of B5W stuff he picked up from several distributor's back shelves. Better choice then e-bay any day IMO, as long as his supplies last...
The old post-closing
AoG website is still up, you can review their stock list to see what they made (and get an idea of how all those ships are supposed to look), and you can still send a message to Agent-1 under
