Are the hobbies and pastimes the same or similar to what we have on Earth? Equally if the world is totally different from what we know, presumably the hobbies and pastimes are as well so what form would these take?
Can anyone take part in hobbies or are they restricted to the rich and/or others in favour with the ruling powers? Does your fictional world encourage active, sport like hobbies or more artistic ones? Is reading encouraged? And is there freedom to read whatever your characters like or are books limited to what the government prefers people to read? Are writers treated well? (It wouldn't surprise me if they're not. A sure sign of a tyrannical regime, in fiction or otherwise, is when writers are controlled).
