: I can't imagine this hasn't been asked before. But never by me :D
: Marathon 1 has wonderful music. So good as a matter of fact I frequently
: listen to it at my leasure, while doing homework or doing internet stuff.
: When I first purchased M2 I was excited to insert the disk and have the
: music tracks and my disposal. However M2 or MI have no level music. Why
: was this choice made?
Like Everyone Else said, they didn't make music for Marathon II and Infinity because they wanted to show off their Panoramic 3D Ambient Sound. This was a wise choice because this was the first FPS to do that. Marathon II did for Background Sound what Marathon 1 did for mapping. First to have a full 3D Skybox and Texturemapped polygons in their maps. Marathon Contributed A LOT of concepts to today's FPS making Techniques.
