PRISM/AGENT is a hack of GHOST/ECHO that I am working on which is inspired by Captain Scarlet and the Mysterons. It has been rolling around in my head for a while now to create something "complete" - something that is done and I can play it and move on. Not just to have ideas in my brain all the time with no escape. I think PRISM/AGENT (which is a name-in-progress) is the first way to defuse that creative bomb which, if it explodes, will make me bitter and annoyed and sulky.
I love GHOST/ECHO. I think I've said that before on here. It's just beautiful. Two pages, some inspirations, some simple mechanics that create rich stories. PRISM/AGENT is an ugly little runt, built out of the best bits of other things, but hopefully it will be playable. I see it one way in my head, and others might play it totally differently.
Core ideas are that PCs are agents with colour codenames, as the Captains in Spectrum are; agents have been freed/released/rescued from aliens/others, but as a result have gained Influences (equivalent to Channeling the Ghost Field move in G/E). These Influences are based on the powers that the Mysterons show in Captain Scarlet, but that's it: the agents can use these powers, but if they lose control of them something bad happens. Basic moves are similar/identical to G/E, which of course are based in part on moves in Apocalypse World I think. The Listening For Echoes move is translated to trying to uncover the intention of the Others (Obscurons?) - and if you fail at that then something bad happens (the Others become aware of you, or you face some kind of mental assault).
But here's what occurs and which I am excited about: PRISM/AGENT has the possibility to be really neat in that you can take the basic premise and transplant it to so many different locations and time periods. A retro-future like Captain Scarlet? Check. A 1920s gangster backdrop with Others/Invaders? Check. Straight pulp heroes? Check. This was something that GHOST/ECHO did beautifully - you don't need lots of stuff in order to play it, and to play it in so many different ways.
Anyways! PRISM/AGENT - or something similarly (or not) named. Coming soon. Playtesting over G+ maybe by the end of April, or in person in Liverpool (Liverpool Game Nerds Assemble!). Comments and questions very welcome!
