The main theme of RuneScape runs through much of the music of the game. It has two versions: the Old School RuneScape (“OSRS”) version makes use of low budget midi instruments and is packed with exciting rhythms and decoration; and the newer RuneScape 3 version, which has flowing orchestral lines.

This arrangement tries to incorporate both the musicality of RuneScape 3 and its lush orchestral textures, with the energetic drive of the OSRS version. To that end, rhythmic ideas and decorations are borrowed from OSRS and superimposed onto a framework provided by RuneScape 3.
