Legend
How many science fiction stories are set in the far future, with interstellar FTL spacecraft and huge space fleets, a return to some form of nobility and royalty, with rugged colonists and settlers on distant worlds?The Grumpy Celt said:(And be honest – how many fantasy fiction stories are set is some pseudo-Middle Ages setting, with some order of knights or warriors, some order of wizards or magic users and pretty people imperiled by dark powers?)
How many crime/mystery stories are set in a big city, with a highly experienced protagonist who has seen it all and is an expert in his field, and typically has a younger and less experienced ally who serves as a literary device to explain everything or provide another generation's perspective?
How many love stories are about a young couple who meets and falls in love at first sight even though they are from completely different backgrounds, even if they don't realize it immediately, but they come to quickly enough, and have to overcome disapproving parents or friends?
Every genre has it's standard forms, the things the audience generally expects. The pseudo-medieval concept is pretty standard to fantasy, just like space opera is standard to sci-fi. You can have other types, but it's a well acknowledged main form.
