Last, how about a nod to the old Sierra 3-D adventure games of the 80's and 90's? Games like Kings Quest IV, Space Quest III, or Hero's Quest (later renamed Quest for Glory):
(Side note - I had an original Tandy 1000 (4.77 MHz 8088) with 3-voice sound and after "upgrading" to a Gateway 386 I was appalled at how bad the regular PC speaker sounded. These games literally drove me to buy an 8-bit SoundBlaster just to hear the soundtracks. To put this in context, the game boxes had ads *from Sierra* to buy an AdLib card or a Roland MT-32 just for the soundtracks.)
