Yeah, I thoroughly enjoyed their John Carter of Mars core rulebook even though I don't think the 2d20 engine is very playable, intuitive or fun. Like you said, if the fluff and setting info is good, along with some nice art, I'll buy it. Or at the very least I'll do a video of it.
Any way you slice it, that's a lot of cooks in the kitchen. I'm not surprised there's not much press yet. I just hope 1) It gets finished and 2) it's done with love.
