Yes, I would highly recommend it, it's sought after by many fans.
The fact is, Dracula X Nocturne in the Moonlight is the same name on the Japanese PSX verison as well.
While we've always called it "CastleVania Symphony of the Night"
The Saturn import actually gives you so many extra goodies that the US verison missed out on. Like two extra fimilars, The Angel and the Gremlin.
One neat feature I like, is equip the Angel fimilar, level her up to 50...then head over to the Royale Chapel (in the normal castle, not inverted) an sit in the confession booth chair.....sit there for more then 5 minutes....and watch what happens with the Angel fimilar....she'll calmly sit on Alucard's shoulders.....and bust out with a hidden track...and start SINGING with japanese lyrics....it's quite a lovely treat...
