I'm creating a space opera video game and I was wondering if to be considered a Space Opera it had to feature some supernatural abilities like Star Wars has with the Force. Or can I completely forgo that entire idea altogether and keep the rest of what the Wikipedia page says about Space Operas?
Space Opera arguably originated with E.E. "Doc" Smith. Many of his stories (the Lensman series, most notably) depended on psychic powers, but many did not (Skylark series, the independent novel "Spacehounds of IPC", and others). What makes them space opera rather than true "science fiction" is primarily that the story didn't depend specifically on the science to work (Hal Clement, by contrast, is well known for stories where the whole thing falls apart if, for instance, set in a different environment from the extreme one he wrote that story in; Arthur C. Clarke likewise).
Sometimes its hard to tell a space opera from science fiction, but my rule is to ask myself if it'd be an equally sensible story if set on a tall ship with black powder cannon, or in ancient Egypt, or in modern day Earth with Glocks in place of the laser pistols or blasters. If it would, it's space opera, with or without magic, psi powers, aliens who look like men in movie makeup, and so forth.
