Well, I probably wouldn't have bothered with Requiem For Methuselah, except for my introduction to Michah Brack in Federation. The Reeves-Stevens usage of little tidbits in Prime Directive and Federation made me pay more attention to The Savage Curtain, Omega Glory, Requiem, and quite a few other original episodes that are not necessarily bad, but average. The nod to the Gamester of Triskelion in The Final Reflection is fun, but it only makes the Gamesters interesting in the sense of anchoring them in galactic politics. For some reason I think there was a book that referenced Whom Gods Destroy, but I'm not sure. Maybe it's just Garth's history that interests me on it's own merits.
