I'm having a bit of trouble finding an idea for a sci fi story which will not be depressing. One of the reasons high fantasy is so popular now is that it is a form of escapism for its readers, whereas people are afraid of the future, and shy away from depressing stories in dreary times like these. (Which is one reason why sci fi is in decline in the literary medium.) I have a few ideas, but ultimately for a Sci Fi conflict in the real world, the only antagonists that could exist are either an alien government, or a human government, and those simply throw too vast a pool of resources against the protagonist to make victory or joy realistic. Thus, the book would be depressing. I don't want to plot or characters or anything. It would be lazy and pointless to ask the community for their hard work. I'd just like a couple lines of text or something which could give me inspiration for a conflict which wouldn't by definition have the protagonist fleeing for his life for the entirety of the book. It can be anything- near future, distant future, aliens, genetic engineering, a dream, etc. But it has to have room for happiness and/or victory. For example. . . The traditional roles of aliens and humans in sci fi are reversed, and humans are invading an alien world, either peacefully or otherwise.
