Interesting that "BEM" was conceived that far back. Of course one wonders how that would have played out in live-action. Live-action in the '60s would never have been able to pull off a colony being (maybe a good thing considering how ludicrously it was done on TAS) and a tribe of bipedal lizards would have been beyond them. One (like a Gorn) you could do, but more than that forget it.
Some years ago I read The Joy Machine.
Uh, no joy in it. It really read like a story idea rather than a genuine TOS adventure/drama. That said it could have been worked into something passable, but as is it reminded me too much of "Return Of The Archons."
