GTA V has some pretty neat soundtracks, original score or otherwise (We Were Set Up and Minor Turbulence personal favourites). I personally love This Is What You Are from Warframe but the rest of the OST is pretty average. Minecraft's soundtrack is beautiful. I also really dig some of the ambient and combat themes from Borderlands 2 and the Pre Sequel (Vorago Solitude Ambient is really sinister and dark).
