You really should stick to Star Trek.
As opposed to what?
But it was "good" vs. "evil"
Of course, the question here might be, was it?
That the Excalbians say that the teams are divided along those lines might be sufficient proof to the contrary. Why would they give the game away?
Interestingly, the dialogue suggests that other characters were previously captured and forced to play the game, with "power" as the prize for victory; we aren't told who those were (were Kahless, Green or Lincoln perhaps among them?) or whether they won or lost. Were those games about good vs. evil (too?), or about something else?
