Science-fantasy. To me, that is the combination of sword and sorcery and hightech science, mainly as seen in Flash Gordon and other such sources. Trying to combine these parts results in a mishmash resembling some Sunday morning cartoons from the 80's, for good and for bad.
As I am currently trying to write a scenario for an rpg session I am looking for ideas to include. Therefore I ask: what is science-fantasy to you?
