What is your favourite kind of science fiction? Alternate history, space adventure, military SF, time travel, near future, alternate universe, science fantasy, superheroes, social allegory, whatever. And, of course, different kinds can be mixed together, but what is your overall preference? Of course, execution makes all the difference, and so that's why over the years I can enjoy different types of SF. But overall my preference is for space adventure. Sadly at present there's little real space adventure to be had. Anyone else?
