I don't think its completly rubbish. I could see why some people would think so. In fact if they ever wanted to put both worlds together that would be the best way to do so.When I was much younger and just getting into the hobby my cousin told me that the WHFB world was actually a planet inside the Eye of Terror and that Sigmar was one of the lost Primarchs, among other rubbish... This isn't true, though.
But sometimes it's nice to wonder...
But might that not backfire when they eventually go online or talk to other gamers who hold to canon and they decide daddy was a bullshitter?with the first and second editions of warhammer, sigmar was at the pinnacle of god/hero worship. sure, with the publishing of the sigmar series by black library, hes legendary status has gone from "super-awesome-mighty human wielding a great warhammer" to "just a lucky guy who was at the right place and right time", but, i think you can look at the stories and compare them to something like "decent of angels" or any other books about the primarchs and see some similarities. a man with no equal, able to unite the local human populace against a common enemy, chosen by the people to lead them, had a signature weapon.
myself, i tell my friends, and when my kids are old enough to hear the stories, i plan on telling them everything i know about the primarchs, and ill include sigmar in those ranks of awesomeness.
I'd have to say "Not Really", he didn't unite the entire world under his leadership. He didn't even unite all the human tribes, Bretonia & Kisliv may have allied with his Empire but they don't worship him. Plus all the humans in Cathay didn't even know about him.nailed it on the head, baron.
sigmar is like the primarchs in how much of an effect he had on the world.
Angron, Perturabo, Mortarion, Ferrus Manus, Alpharius, and Rogal Dorn didn't unite or rule their worlds either.I'd have to say "Not Really", he didn't unite the entire world under his leadership. He didn't even unite all the human tribes, Bretonia & Kisliv may have allied with his Empire but they don't worship him. Plus all the humans in Cathay didn't even know about him.
I'm just saying that most all of the Primarchs rose to a postion of dominence over their entire home world, Sigmar just united one smallish nation of his.
I'd think if he was a "True" Primarch he'd have united all the humans on the planet and set about destroying all the other races or at least beating the back so they would no longer be a threat to humans. Just look at what the Lion did on Caliban. I just don't see the dominence and power of a Primarch in Sigmar.
I haven't read any of the early history Fantasy books yet, so I don't know how he's protrayed in them.
Just my opinions, it is an interest theory and may have been something GW considered to be fluff in the early days but I think they've mostly ret-coned it and gotten away from it.
