Switching gears a bit, I am not going to suggest another way to make your campaign cool but instead a way to make your GM technique effective. I have touched on this subject before, long ago it seems and I rarely see anyone else mention it so, here goes nothing...
Picture an average* RPG session with an average* GM and an average* group.
You've got the GM sitting at the head of the table, sometimes behind a screen of charts and/or notes, with the players likewise around said table, snacks and drinks in the center or in front of each person.
Now look at this if you would...
I stand up when I GM. I move around. If a major threat or tense situation threatens a PC, I move in toward that player very quickly...than ask them what they do as I slowly pull away. I raise my voice for shouting villain and lower it to a whisper for nervous informants. I spin, I bounce, I wave my hands in the air (often, like I just don't care) and generally avoid remaining static.
I almost never describe hallways or tunnels as "Ten feet by twenty feet". I say, "It's the same size as...you see that door there? OK, from me to the door."
I will use your snacks as props. I will, and often do, place your soda cans and orange juice containers in the postions that roughly illustrate when the incoming fighters are located in relation to your Free Trader ship.
Part of the reason for this is that I find engaging the players in this more animated way gets them more excited and involved in the game. As inspirations for my gamemastering style, I look to famous entertainers and directors and especially MCs who were (or are) skilled at holding the attention of a crowd. So moreso than Gygax and Greenwood, I try to emulate P.T. Barnum, Gilda Radner, Jane Curtain, Johnny Carson, Steven Spielberg and various stand up comedians. These men and women are people adapt at timing, staging a scene and (and this is key) misdirection. David Copperfield and of course Houdini are also people to look to in this regard.
Are you ready...coming full circle...
One of the reasons the approach detailed in my previous post works for me is because I have studied and adapted the techniques listed above. I am an expert at stalling, looking like I know when I don't, or maybe I do. The GM is smiling and looking toward the Pilot PC; Is the ship in danger of crashing after what the Engineer just did to fix the Manuver Drive? An innocent, sad puppy face and be as scary to players as an evil chuckle is played at the right time. A favorite phrase of mine after a particularly daring move and an important roll is (after staring at the dice and blinking dramatically, followed by an 'aw shucks' face), "Wow. And I so liked your characters...".
You are more than the referee. You are a Showman (or Showperson if you prefer). You are there to direct, to dazzle, to entice, to excite and to entertain. Maybe no one else wants to. Maybe you are just the best at it in your group of gaming friends. Whatever the reason, the spotlight is theirs but the camera is yours. Welcome them to your Show of Shows!
*Zak would scoff at the term 'average'. He would be right to do so (and he would also be getting nitpicky over semantics but that's neither here nor there.). Suffice to say that what I mean by 'average' in this instant is 'what you encounter most often if you surveyed the lot of us gamers the world over'. If that is too confusing for you or rubs you the wrong way than I'm using to mean, 'that which helps me illustrate my point' and we'll leave it there.
