I'm glad to see the Terran Empire has its fans! I always loved it, and I'm sorry I was never able to put a group together to explore it. I'm also sorry DOJ decided to abandon it so quickly before it got a chance to develop. When I read Steven Long's post that DOJ was not going to support the STAR HERO line anymore due to poor sales, it broke my heart.
Had I been able to get my own TE campaign off the ground, I'd meant to set it in 2636 CE, not long after Marissa III's reign began. The sourcebook is terrific, with enough aliens, political intrigue, plot threads, and all else that I'm sure I could've kept a campaign going for a while. I agree with the idea the setting would've benefited from having some "official" modules devoted to it from DOJ. If they'd pushed the setting more, it might've developed more of a fan following, and it might've grown large enough to keep around, much as CHAMPIONS has survived down through the years. Certainly TE can be converted to Sixth Edition HERO with just a little work; it would've made a great complement to the revised STAR HERO.
Back when Steven Long wrote the Writers Guidelines for the Fifth Edition (has it really been so long ago?), he mentioned DOJ might also be interested in fiction collections set in the HERO Universe. To anyone's knowledge, has there ever been any fan fiction written for the Terran Empire setting? I was intrigued by the idea of TE fiction, so much so I actually sat down and wrote a first draft out for the 2018 National Novel Writers' Month contest. The story was weak, but it was fun to write and helped me realize a full TE fiction series could be possible, in the hands of a writer more gifted than myself! I doubt a TE fiction series is gong to happen at this late date, but if someone were to attempt it, do any of you think there's be an audience for it?
