You can play the Intense Battle Full Loop to get an appreciation of what it sounds like (Note: the audio file is watermarked if you are wondering why my voice disturbs you gently half way through :)
The loops are very short, only between 10 and 32 seconds in length, making them especially suitable for small games with shorter gameplay. The short duration also makes them incredible cheap with excellent value for money as they are practically given away priced between $3 and $10 each for indie game developers.
Details for the curious
To create these loops I use Steinberg Cubase 5.5 as a sequencer. The orchestral library I use is Symphonic Orchestra Gold by EastWest Samples / Quantum Leap. I've set up a, for me, gigantic Cubase template with the full Orchestra and all instruments articulated with keyswitch instruments. The keyswitch means that I can select articulation for each midi note played to say how it should be played, e.g. the keyswitch for 18 Violins section contains no less than 23 articulations such as marcato, sustain, slur, tremolo, legato, lyrical, expressive, quick up down, etc.

The orchestral template is very memory hungry and to accomodate this I'm running a Intel i7 950 processor @3.07 Ghz with 24 GB of RAM memory. I've stored all the orchestral library files on a 256 GB Crucial Solid State HDD because the library consists of 39983 files (32.3 GB) and it took forever to load it up on my previous 7200 RPM drive. This is running on Windows 7 x64 Ultimate and I must say that this combination works a treat. I can also take this opportunity to mention that the setup and music software is funded by my every day job as an IT Consultant and NOT from Imphenzia Soundtrack licenses - I've got a long way to go for that to happen =)
Here is also a screenshot of the Key Switch articulations I've configured. This one is for the 18 Violins sections so I had to configure the same thing for all instruments in the entire orchestra which took me the closest thing to forever.

I should also mention that this particular piece of music uses percussion from Stormdrum 2 and a little bit of choir from Symphonic Choirs.
