Okay I'm all for the original setting at long as the adventures are the same come one the defeated Apollo, fought Mobsters and beat up on Nazis how can you go wrong AND the uniforms are the cute 60's dress things for the ladies. 
Well, if we go with the 60s outfits, that would be prior to the movie settings but I'm more than OK with that. In the later TOS movies, they had the red uniforms with the white trim and bars, if I recall.
But yes, you're in the right era, Ruby. Love the TOS memories. The Horizon game would be the one where the book was left behind for your mobsters in "A Piece of the Action." But we'll save that game as stated before.
Speaking of which, are the roles going to be gender limited like the original series, or are they going to be more open? I'm fine either way, I was just curious.
And who's captaining this thing? You, DA, or an NPC or a PC?
No gender limitations. Roddenberry didn't intend there to be any and I'm not going to have any. It just was a tough sell for the networks. Remember, in the Cage, the original number one was female.
As to Captaining, it would be me or an NPC by me. Either way, it is me. :) I have found that's the easiest way to throw overall plot at folks.
I'm going to step aside. I'm not fully caught up on TOS yet and it looks like this is invariably going to contain spoilers. Nothing's been messed up for me yet but I'd rather not risk it. Have fun everyone.
Spoilers? Not sure what you mean but feel free to keep it open. Always room for new crew members if and when you feel ready.
That's true. The short skirts are a plus.
Hm. Looking like the TOS era during the TV show is winning.
