Arnie's Terminator theme & Metamorphosis are worth storage space. The others...not so much. Have a thorough listen yourself b/c this is subjective sheat.
Wow... what an amazing OST!! And to think, if Sunsoft would've got the Terminator LLC for NES, then you're talking about 2 of the best soundtracks ever produced in gaming history!!
composer: Tommy Tallarico, with Brad Ira Fiedel ("The Terminator Theme"), Bijan Shaheer ("Future Shock"), Joey Kuras ("Visions") and TeknoMan of Teknologic ("CyberTek").
