Here's a nifty trick I tried based on advice in the Doctor Who: Adventures in Time and Space RPG: Previews of the next session! Now, DWAITAS is strong on genre emulation, and since it is based on a tv show, it recommends you make your sessions like that tv show. And I'm not far off as a GameMaster. RPG campaigns as a medium are episodic, just like television, and I've experimented with "teaser" moments, soundtracks, subplots, etc. to give them that television vibe in the past. And yet, I'd never even thought of doing previews for the coming week/session.
And now that I've tried it, it's definitely going into my GameMaster's toolbox.
How I Do It
I write a little script with maybe a dozen things on it. Some are images which I will read, some are lines of dialogue (I try to include one for each Player Character). I hand out a few copies so that we can all read from it. With a little soundtrack in the background, we have a go.GM: SCENE - A burnt out landscape.
No Nonsense Companion: This isn't Woodstock, is it.
GM: SCENE - TARDIS interior, dark except for a few lights.
Timelord: WhoaWhoaWhoaWhoaWhoaWhoa, no no no...
Hyperactive Companion: The TARDIS can't die... can it?
GM: SCENE - The group walking through the wastland.
VO/Timelord: We must find something to repair it.
GM: BEAT (a beat is when the images are cut with a fade to black each time, you know the ones I mean) - A robot spider attacks the camera.
GM: BEAT - The Timelord's face as an unknown woman says "Need help?"
GM: BEAT - The eye of a Dalek
GM: BEAT - Physical Companion answers her: Yes.
In the above example, I put a blank where the word "Dalek" goes so as not to give it away when they received the hand-out, but it really doesn't matter. The important thing is not to give too much away. A few lines that would be expected in the first 15 minutes of a show, a reveal of an important guest-star or monster, and don't be afraid to mislead the players. That's what tv producers do too! Your announced threat may not be one at all, just a line taken out of context, for example.
What It Does
The preview has three distinct effects and uses. First, it creates anticipation for the next session. I've found players even more committed than usual because they can't wait to see what the preview MEANS. If you've done your job well, it'll feel like a puzzle and pique their interest.
Secondly, we've found it's great fun to make sure those images and lines are delivered in the actual session. Players re-read the preview for themselves at the start of the next session and find a place, somewhere, for those lines. It's even more fun when a player has obviously missed the opportunity and finds a way to say his line much later, recreating that "misleading preview" effect for himself. Generous GMs may even reward players that cleverly lay in their line or moment.
And that leads us to the preview's third effect: Guiding the story. If the preview shows the characters in a jail cell, then they must have gotten captured. Will they surrender more willingly when the time comes? (The answer is yes, by the way.) So in the above example, my real story takes place somewhere out there in the wasteland, so I have them leave the TARDIS. They might roleplay a scene where they try to fix the ship, but they already know they must leave it at some point. And they will. Railroading? A bit. But the preview makes it a smooth part of dramatic necessity by making the players willing participants. In a traditional role-playing game, I might shipwreck the crew on alien shores, and then they might putter around the ship instead of exploring. I'd have to create moments that attract them away or strongly hint that the fix is "out there". This way, no GM interference is required and the players make it their own idea. In a game like a Doctor Who RPG where the whole of space and time acts as a canvas, the preview is a good way of announcing where the TARDIS will land so that players can actually choose it to be their destination. And since anything is possible, guide posts from the preview can help structure the game. This is why it's a good idea to only put your set-up in the preview. You don't want to dictate the climax, the players' solutions, etc.
The Next Step
We played three times this week (thanks Spring Break), and read three previews. They were great fun to read and to later insert in the "completed episode". The next logical step now that players are familiar with the device is to allow the players themselves to improvise their lines. These could be "blind" lines that are generic enough to be inserted into the next episode (or completely crazy and fun to someone shoehorn in), or they could be in response to images and NPC lines you throw at them.
See? I'm not a tyrant. They'll be able to use their own voices soon enough. After all, we're "writing" this story as a committee!
