*checks own RP's*

Nope, all on-going is 'original.'

So it can't be everything. Claim dismissed.

As for originality... Most fantasy worlds we're going to come across will have elves and dwarves. Modern fantasy will hit you with werewolves and sci-fi will very likely be about space travel. Besides, you could make something 'totally original' but it would be very hard to find players because you're trying to sell people things they don't know. This is why we use genres as descriptors to begin with. This is why you always include entry points in the shape of familiar elements, ways for people to grasp the setting. This unoriginality makes RP's work. I mean if I told you we would now be in an RP set in someone's liver and we'd all be like Osmosis Jones trying to prevent the body from getting sick, but with a lot more accurate anatomy, it'd be pretty damn 'original' but nobody would play it because they really wouldn't have a clue what to do. Yet if I say you're all chosen knights to find the 7 crystals in a fantasy setting, I could start an interest check with just that and everyone and their dog would know what to do. Both concepts have the same amount of depth, both have a goal, but I can guarentee the fantasy one will do better.
