I remember seeing those, but I did not have them. However, I do have the Games Workshop Stormbringer 3rd edition and that game is awesome.
Why? For me, GW's Stormbringer 3rd captures the spirit of Moorcock's writing while making a brutal, extremely playable RPG. Its been my favorite Sword & Sorcery RPG.
People can nitpick about how accurate the magic is to the setting, but
Stormbringer is unquestionably one of the most fun fantasy RPGs ever. The second RPG I ever played after D&D was the first edition of
Stormbringer. After one session of that, I went fifteen years without playing D&D again.
My Stormbringer's binding fell apart within the first year, but the pages have stayed in the book far better than my original Rogue Trader.
The crappy binding on GWs books was so infuriating as so many of them were works of art. I remember my copy of
Realms of Chaos began shedding pages the first time I read it.
At least most of the Mongoose books I bought that fell apart looked like Mongoose books, so it was easier to take.
A dozen years ago, I got invited to guest GM for a friend's group for a Stormbringer mini-campaign and I was pre-warned there was a canon junkie in the group (he canon junkies everything for every campaign) so we began the game on a merchant ship bringing tribute to Elric's parents who sadly lost their teen son to a sorcerous death and even sacrificing Elric's cousins to Arioch did not revive the child. Yeah, I pre-murdered everybody.
I love it.
I know that there are some big pivotal events that take place in the Elric Saga, like the sacking of Melnibone and that thing where the whole world ended, but the books are mostly Elric off having adventures, and Moorcock is a writer that works mainly by gonzo imagination than having a meticulously crafted setting.
It just seems a weird setting to get all hung up about canon with. It's as if there were people out there that got obsessed with the canon of
Doctor Who, which is equally flying by the seat of its pants.
