Castlevania: Symphony of the Night (1997)
Few original PlayStation games are as revered as this one so I'm very pleased to say it's one of the couple of dozen that I actually own! I very much doubt I'll get around to giving it the coverage it deserves for a good while yet but it is of course a thoroughly splendid game in pretty much every way. One particularly noteworthy way is its amazing soundtrack by Michiru Yamane which features over thirty songs spread over a typically eclectic variety of styles including classical, rock, techno, and jazz. My favourite tracks, however, are the gothic ones like this fantastic piece:
Special Note: I didn't record this great tune myself, I'm just an admirer, so all credit to, firstly the original composer, and secondly the YouTube user who uploaded it!
