All the Halos
Wolfenstein new order had a suprisngly good one
payday 2 had the good donks
ive never played dark country or even know what it is but fuck the soundtracks good
Fallout, and im not talkin just the radio shit, the OST's especially from 1 and 2 are mint
all the S.T.A.L.K.E.Rs and i guess you could lump Metro in there
BF2 was probably my favourite rendition of the theme
