Final Liberation wasn't a 1:1 translation of the rules for Epic 40K (which was never nearly as popular as 40K). It only had, I think, 3 incomplete armies. Its terrain was kind of anemic. Plus it was pretty clunky watching your little guys move around and fire. And you couldn't paint or customize your units. So there was a lot going against it.
I'm just inclined to think that an actual 1:1 tabletop simulation would do for their bread-and-butter tabletop game what the Internet has done for newspapers. Good for consumers, but kind of hard to spin into something that's in their best interest, even as price gougy as they are.
