True that there is a lot of opportunity for overlap. I like to tell the story (stop with the eye-rolling!) of when we first play-tested Pete's 'Dreamtime' game idea, where we played characters who would shift between three realities. One was Iron Wind, one was a near-future Cyberspace, and another was a far future star empire (Space Master). We were playtesting a simplified system, but a lot of the game was just role-playing as we began to realize that our character's spirits were dreaming in three realities. I loved it, since I liked the role-playing aspect, but some others I think did not like it so much, since there was not a set rules structure. Anyway, in the star empire, I played a Pierson's puppeteer (Ringworld) and wore two sock-puppets, each with a styrofoam eye. I'd use the puppet to roll dice, sometimes the heads would look at each other. And of course I played him as a total paranoid, even though he had to be somewhat insane to work with humanoids. In the near-future, I worked for the Interplanetary Geographical Society and had high-tech glasses, in the shape of the NatGeo yellow rectangle, that had some kind of special nanotech powers. Naturally, I made a prop set of these. So, not sure how far off the deep end that kind of play was.
