I am not going to say yes, but there certainly is sufficient backstory to support a novel

sufficient backstory for a novel but not for a campaign?

Craig, give us a campaign editor and some more game options before telling us about the potential for a novel. We'll write an entire universe for you if we have good tools.

I've toyed with making campaign-ish maps, but there is only so much Galaxy Forge allows. See (invasion map) and (rogue vengence map) for 7 Deadly Sins 1.3d for example. Given proper tools, I can make these maps and future maps sing volumes.
I even used to fiddle around with FRED2 for Freespace2 and damn if that wasn't fun. The battles and story elements made by the community enriched the game beyond imagination. Give us something on par with that and you won't be disappointed. You might even get enough good campaigns/stories for several books.

The present exclusion of a campaign has nothing to do with story, but with the budget and mechanics (polishing the core gameplay was decided to be more important than a typical ten-mission tutorial campaign). As has been said before, we hope to do a campaign in the expansion.
