What about the music?

[Ephestion]

If i wanted to make some music for the different civs how should they be made? mp3 format, midi, other?

And what types of music will be needed: themes for when users Attack, Idle, Peril (being attacked) etc?

The game engine requires all music and sounds to be Ogg Vorbis.

Currently we just have 'peace' and 'battle' tracks, but we don't have any dynamic music selection implemented in the engine so I'm not sure how it'll end up working. (Probably depends largely on how wide a variety of decent music we can get made, and whether we can blend between them sensibly without it sounding terrible, but I don't know any details.)
