Certain developments in console and arcade games correllated directly with DRAM pricing at that time. Before 1985, music was usually limited to short jingles and the game content usually just had one "world" to it; afterwards, in the face of rapidly falling prices, nearly every new release had a soundtrack of a few minutes length and multiple themed settings. The 1988 shortage led to some games with cut content, but more often just delays on release as with Zelda II.
