To me video games are one of the most fascinating mediums of interactive art, as they involve skills and techniques that draw from all different mediums whether that be
– Narrative
-Music
-Atmosphere
-Coding/Graphics/Mechanics
-Concept/Otherworldlyness
So doing the sound for a game would mean knowing where you fit as a cog in the machine , as video games are so multi layered. This would include foley type sound which is traditional sound for screen stuff combined with ambient synthy stuff , but it all depends on the subject and what’s on screen!
