The thing is, with an RTS, you have much more protracted playing sessions; up to a good few hours for one game. Hence, I would imagine that the music is going to be lighter and less dramatic, in order to allow for user actions; the Halo theme may work great in Halo 3 when you're kicking covenant ass, but do you really want that same music to pop up whilst your collecting resources etc.

I trust that Ensemble will provide a suitably good soundtrack; the Age of Empires one have always excelled, so I'm sure we're in good hands :)

of course not during the less dramatic sequences, but there you can still have good and quiet music, building up to the combat. Also in the campaign you can have certain sequences where the heavy and dramatic music appears.. a good example if you ask me is ground control 2.. there were some sequences were the music was just great and the timing just as good.

First of all I am a huge HALO fan and if bungie trusts you guys to make a great addition to the HALO family I am all for it.  I have watched the trailer over and over and I was missing something.  The CG work was great and it was great to see the type of environment that will be created but I got to say without Mr Odonnel's music it feels a little dry.  I went back and watched the Halo 3 trailer and a huge part of the trailer is how the music score pulls you along.  This looks like a great project and I am already a huge fan, but we need better music.

 No music makes it a bit more serious and more realasistic like a real battle. Because in a real battle nobody will be there with a god damn radio and playing it whilst everybody fights. :)
 

Marty is part of the Halo game. For me he isone of the most carysmatic members of Bungie. Since the frist time I saw him, he was someone at Bungie that i feltthat is part of the success of halo.

Halo music is something i love in the game, music is as gameplay and History the most important things of Halo. 

Waiting for more details music and sound of Halo Wars, interesting.

Martin O doneil is master, the best.
