TSR's Top Secret Anyone?
Are we talking Top Secret or Top Secret/S.I.? I'm good with either one. It's my second favorite genre after science fiction!
I grew up on The Man From U.N.C.L.E., I Spy, Secret Agent, Get Smart, Mission: Impossible, Our Man Flint, and, of course, James Bond! And I bought and read all the books out at the time!
Translating all that into a game isn't easy, even for proactive players since we can never be sure where the Administrator is leading us!
