Yeah, the thing with HBS BTech was that sales-wise it didn't do bad, especially since part of the development was backed by Kickstarter, and it was popular enough to get expansions, but after all the rights holders etc. were paid out the cut simply wasn't big enough to continue working on it. That being said, I can genuinely recommend the Hyades Rim mod for HBS Btech as it basically gives you the sort of story-driven campaign that HBS couldn't. It also makes the base game a lot longer and more challenging.
