The most popular example of military fantasy would probably be the Black Company, a novel series oft quoted to be inspiration but most people have not read it. I have. It's a peculiar series, but it lacks a lot when it comes to the actual military stuff, as fitting for someone who can't be bothered to write everything down as the Annalist of the Company.
Sadly, despite having a few novels that fit the bill, military fantasy is not a very well established genre.
Ooh, good one. Hm. Another I really want has been already referred to, the blending of science fiction and fantasy. Which, really, when you get down to it, is two
huge umbrellas. There's so many strains in there.
There's more conventional fantasy stories that just so happen to take place in worlds that are ostensibly working more or less like fantasy worlds, but with sufficiently advanced technology (think
Star Wars, and
Warhammer 40,000) which we might call science fantasy, and then there's wildly fantastic things that engage science in some form or another (
Sandman: Overture or one of my personal favorite novels of ever,
A Wrinkle In Time), or even things which push the distinction even further, like all of Gene Wolfe's
Book of the New Sun. And other things that don't really fit into the mold in a convenient way like
Hyper Light Drifter which is this gorgeous post-apoc science fantasy game, very clearly inspired by
Nausicaä of the Valley of the Wind. Also, anything and everything that gets close to Michael Swanwick's
The Iron Dragon's Daughter makes me very happy.
I'd like more of those.
I'd also like, hm, more things that are very forward about their anachronism. Bad examples of this are
Naruto but good ones, like
Saga, like
The Flintstones, and so on, are just very powerful. I'd like to see lots more of that sort of bending of setting. What else...
Often times I like my fantasy to be drenched in a time, of some quality. It's either of a time and a place, or heavily based off of one. Merge the fantastic with a time period and go all the way in on it.
Princess Mononoke is Muromachi-era Japan, for example. One of my favorite fanfic writers here,
@EarthScorpion, likes this a lot too, and I believe he turned the setting of
Familiar of Zero into more or less 1600s Belgium? He could talk more about that if he feels like it.
That's about all I can think of.
(Wow, this is a bit off-topic. But w/e.)
