as most of us know, there's no sound in a vacuum, since the sound waves don't have a thing to move through (which, on earth, is the air), hence the saying "in space nobody can hear you scream"
in SR2, there's still sound in space, and it would be a nice addition if there was a switch in the sound setting (like "Mute sound in vacuum") that mutes the game sound effects (i.e. engines and rotators and stuff are muted, but the music and UI button clicks still stay), with it of course being toggleable for those who want to hear their engines scream, this would give a minor boost to realism and probably isn't too hard to implement
(idk if suggestions have been re-opened or not, but if they are then please move this post there)
welp, this is a thing now, kinda
