In regards to your first bullet: I’ve got at least four folks rounded up for character burning on Dec. 5th. Burning Wheel, here we come! I know, I know, I’m really late to that era of small press. But damnit, gotta start somewhere.
As for OSR, I don’t even know enough about what it is other than reactionary posturing. At least, that’s all I see in my G+ feed (what little there is anyhow). Not to say there isn’t anything inherently good about that, but my knowledge about OSR is awful even in comparison to PbtA or Bully Pulpit or the like. If you find any good reading for the OSR noob, let me know. I’m keen to understand.
Additionally: all I’ve seen of Lamentations of the Flame Princess is pretty ladies (sometimes naked) being devoured by ghoulish monsters or beheaded by angry warriors. No idea what else it’s about.
