Much like in film and tv, sound design in games is something that is extremely important but often overlooked. Bad sound design is actually worse and a bigger turn off than bad visual design. Don't underestimate it's importance. Right now in dust, it's serviceable, but far from excellent. You need to strike a balance between realistic and artificial, as too far in either direction and it sounds boring and generic. To this day, I still think battlefield bad company 2 has the best sound design of any shooter, it sounds simply fantastic, and it takes the enjoyment of playing it to a whole new level.
