I have this idea for a small sci-fi game about more or less dumb astrobots (which corresponds to the players, of course). I want it to take place on asteroids and possibly planets. My main concern at the moment is this: how realistic (in terms of accurate facts) must the game be? Can it be more fiction than science?
I'm asking this because I suspect that people interested in sci-fi also have deeper knowledge in one or more technical areas (such as anything related to space) - they know what's possible and what's not, to put it bluntly. Comparing with fantasy - which starts with the premise that nothing is real and works its way from there - science fiction (as I see it) tends to be more about "this and that isn't possible at the moment, but there is research going on and it may very well be someday".
Is it possible that I'll alienate players by emphasising fiction over science when writing a sci-fi game, even if it's clear that's more about fun and silliness?
