Yes, i am aware of that. But if we were for realism than we would have take out the engine sound as well. Since this is somewhat a game, user experience becomes more priority. And i believe adding few sound effects could actually bring more immersive experience. I don't mean wind whistling sound in space, But sounds for rcs,communications,eva(breathing sound?), ship crackling, instruments could really really be juicy to hear and actually make you feel more like you're there controlling a ship. You're right that game mechanics and assets should be more of a priority. But just basic sounds for the current parts(rcs,science) that are lacking would be greatly beneficial.
