Hi,
how about adding a "play your own music" feature. It could work similar to games such as GTA where it is possible to listend to music conbtained in a certain folder on your PC from within the game. However the OBEYesk twist would be that the Robosaru gets to play his music for the whole server. All the others have to listen to it wether they want to or not. Oh and by the way: Naturally the Robosaru can mute the music for himself if he wants to.
