I would debate Mount&Blade franchise being low-fantasy. Fictional yes, but in no case low-fantasy, as that would require having supernatural elements, which I'm pretty confident have no presence whatsoever in M&B. And that is for the better, in my book anyway, that for me was the biggest selling point back when I was introduced to this game, pure medieval warfare with no spells attached. It filled a niche that was so overlooked back in the day, ultimately becoming the pioneer of a new genre.
Anyone's welcome to debate my argument. Though I remember reading about the alpha versions of the original M&B having some kind of supernatural elements, someone can probably correct me on that, it doesn't really count any more. Also you could attribute Harlaus' obsession with butter to some supernatural force, but that is just speculation
Regarding critique of why you guys are writing about 'stuff we already know', people don't realize these developer blog entries aren't exclusively meant for the existing fan base. These posts get shared on other websites, and they're a good source of information for people unfamiliar with the franchise. They also give insight on inner workings of the development team, which I doubt most of us were familiar with before these blog posts. I think it's good PR work, I enjoy them a lot, please keep them coming.
