Well, its been a while since anyone posted a message here, but reading through it, this is one of the most interesting ones around here.
I never thought of the BFs as bad guys. Partly because I didn't get any until the Legends came out, partly because they all had smiley faces. For me, the bad guys were the Bulls and the FKs (and that was really only their leaders, I became quite attached to the weezils after a while. And Willa was crazy, not evil.
) The DMs were also always on the bad side, but in a sort of noble, Klingon way. The Wolfpack would have been too, but I never owned any.
In my mind, until the arrival of Fright Knights on the scene, there was never a definitively BAD faction. They all were more or less good. True, the Crusaders had an excess of moral rightness, but in reality, they were rivals with the BFs, who were equally good, but saw things a different way. The BFs had the same problem with the DMs, who had the same problem with the RKs. The Forestmen were also good, but they disagreed with the Crusaders, and allied themselves against the king with the BFs, but remained adamantly opposed to any foreign incursion into their lands (also the lands of the Crusader overlords). The Crusaders desperate to keep themselves intact, would ally with the RKs, which would bring the DMs in on the BF's side, and so on and on.
So really, the wars in my games began because of confusions, and the malice of individual characters (mad BF generals, jealous RK underlings, brain-starved witches, etc.) The only truly evil faction was.... hmm, actually, I never had a truly evil faction. I guess I'll have to get the KK2s to remedy that. The whole faction's existence is evil!
