The thread about attract modes got me thinking about sound, and how good stereo sounds and the progression from bells and buzzers to chimes to chimes that played melodies, to bleep-bloop electronic sounds, to digital sounds, background, speech, integrated music, dual-speaker jobs like Flash Gordon, stereo...
And then we regressed.
I believe I have heard the newer manufacturers' games are in stereo and some have headphone jacks.
How important is STEREO sound to your playing experience? Can you even tell a game is in stereo? Are you able to detect stereo sound at a show? Is it much more important now that games are selling straight to collectors in larger numbers (where the games don't have to compete to be heard over each other?
It just got me thinking because I really like the sound on my Crypt and miss that special effect that isn't there on other modern games without stereo sound.
