I think we're on the same page goes as far as the nature of the game, the themes we want from each side, be them fantasy or magic/logically based. I think we still need to come up with the sort of quest that would bring both players together. Perhaps some kind of scavenger hunt sort of quest that would require the verification of both a fantasy and a sci-fi character to say, access certain areas of the world that might be off-limits to the opposing type of role. Or if you wanted to do something other than that, it could be more risky and have to do with combat as opposed to something light/less-stress. Or we could have the quest have to do with quizzes that could mix both strengths from each role at different check points around the world/areas. 

What do you think?
