Well, that depends on how you categorize 'war', I guess. I mean, there's also people who are slave-ganged into producing food and the highly important materials for the war. And the obstructive bureaucrats who can (accidentally) make entire planets disappear, or suffer orbital bombardment by making a ROUNDING ERROR. But if you consider that life in general throughout the galaxy is a constant (losing) fight for survival, then yes, there is indeed ONLY WAR.
So, where does W40k or WH40k as it's commonly abbreviated to reside on the various scales of fiction?
Idealism vs Cynicism: Pretty hard across to the cynical side. There is, after all, only war, no hope.
Sci-Fi Hardness: Prefers to be 'soft', aiming for fun rather than scientifically accurate representations.
Funny vs Serious: So serious, it could be considered to wrap back around to funny. It depends, really, who you're talking to, but for the most part: GRIM DARKNESS...yeah.
Set in the 41st Millenium (or thereabouts, thus where we get the 'far future' part of the tagline), W40k takes place on an epic scale. But first, some background (links are if you want more detail/a better description, and probably not compulsory reading...though very interesting imnsho):
***
The second spread of mankind to the stars was not as peaceful as some wish it could be, instead centering around a massive military campaign to unify the various worlds where humanity had settled. During this time, the leader of all humanity, known only as the Emperor (a supposedly immortal, incredibly old superhuman being, who may or may not have been various historical figures) led the Great Crusade himself. Along the way, he was reunited with his 'sons', the Primarchs (who were actually genetically engineered from his DNA, to aid him in the Crusades, but they were...uh...stolen by the powers of the Warp, which we'll get to in a bit, and scattered across the universe), all of whom had become great leaders on their own planets.
Right, long story short, the Emperor conquered thousands of systems with the support of his Sons, the 'geneseed' of whom was used to create more supersoliders, known as Space Marines. These soldiers underwent a rigorous and brutal training program, with various medical procedures which gave them enhanced strength, endurance, speed and so forth - and this was before they were given power armour. Divided into Legions, headed by the Primarch whose geneseed had been used to create them, the Space Marines were the ultimate fighting force of the Imperium, until the Emperor decided to leave the front lines, and gave control over to his 'first' Son, Horus.
This was a very, very bad idea. Horus was eventually killed, and shown visions of his father being worshipped as a God (one thing the Emperor had always preached against), and himself being utterly forgotten by mankind. These visions came from the Chaos Gods, who basically resurrected him, and imbued him with all their gifts (something which hasn't happened since, to anyone). He basically then manages to turn half of all the Space Marines against the Emperor, and leads a giant assault against the Imperium with the intent of killing his father and stopping the horrible vision he'd been shown from coming true.
Eventually attacking the capital of the Imperium, Holy Terra (Earth), Horus was on the edge of victory. So the Emperor takes a few of his most loyal men and teleports onto Horus' ship. They're separated, but all fight their way to the bridge (or die trying), where eventually the Emperor and Horus face off. Horus is killed, but the Emperor himself is mortally wounded. Abaddon the Despoiler, second in command to Horus, basically halts the invasion and turns every ship he has around, fleeing back to the Warp. The Emperor, meanwhile, returns to his palace, where after a few quick modifications, he is literally interred in the life-supporting Golden Throne for the next 10,000 years (bringing us to the 'present' chain of events). Over the course of these years, the forces of Chaos repeatedly harass and attack the Imperium, but are always driven back (there have been, so far, thirteen 'Black Crusades', which basically consist of all the remaining Chaos Space Marines (or Traitor Legions/Traitor Marines, as they are known) unite under one banner and attack again, plus numerous, smaller attack all the time, usually resulting in the death of billions).

In addition to the forces of Chaos, there are many hostile alien races who would dearly love to see the Imperium (and each other) dead, for various reasons, most of which involve self-preservation, funnily enough. But we'll deal with those in more detail later.
OK, so hopefully that gives a 'feel' for the setting. But let's break it down into key components and areas. I'll try to go light on the stuff that is 'extra', and focus more on the important aspects as far as our roleplaying will go: the Imperium of Mankind.
To Be Continued, probably in another post so you can all know when I've updated it...
