Good to see some interest in the topic.
I do not (yet) have a copy of Dragon Pass, or of the French edition by Oriflam, La Guerre des Héros. What I do have is the 1976 edition of White Bear and Red Moon and the 1977 edition of Nomad Gods (which we never liked as much, since it's designed as a five-player game).
So last week an old friend from Iowa City, with whom I had played many games of WBRM back in the day, stopped in and we played two rounds of the complete game. Of course we used the original combat resolution rules which are very "swingy". You have an AE (attacker eliminated) result on a one until you reach 4-to-1 odds, so combat is really hit or miss. and with all of the... well, we call them "nuke" attacks, from Cragspider, the Earth Shakers, the Stormwalkers, the Dragons, the Hound and the Sylphs, it doesn't really feel much like a tactical combat game.
Back in the day, we cobbled together two triangular map pieces so we could link the Nomad Gods map and the WBRM map over a wider front (IIRC they overlap some 10-12 hexes in one corner) but the games never felt like they really went together. Prax was about survival on the unforgiving wastelands, while WBRM was a vengeance-driven rivalry between two bitter enemies that was usually decided by who got lucky on key diplomacy rolls.
Joerg, you say that there "shouldn't" be pdfs of any of the early Wyrm's Footnotes. Does that mean Greg has aggressively searched out and eliminated any such files long ago? Or something else that I'm not catching on to? I'm not a hard-core collector myself, but it does seem a shame not to be able to dig up some of those early gems and put them to good use in actual games. Back in the day, not all of us were completely obsessed with the euro-centric tolkienesque worlds that seemed to be projected by early D&D, Judges Guild and other spinoff editors, and we found fascinating the wierd and original worlds like MAR Barker's Petal Throne and Greg's Glorantha. Those worlds, as much as Greyhawk and Blackmoor, were at the heart of the earliest stages of our hobby, and White Bear and Red Moon was at the heart of Runequest and Glorantha.
I'll try to take some pics a little later. Sadly, when we were playing, we didn't think about documenting our game, so I'll have to re-create a bit of it.
