Along with Alucard's quest, Richter's quest is once again included, as is a new quest for Maria. You'll have to venture through two versions of the castle, finding all the important relics to unlock your way, and interacting with Maria Renard and Richter Belmont (heroes of Castlevania Dracula X: Rondo of Blood). You are Alucard, tasked with venturing through your father's castle, besting monsters, collecting items and powers, and becoming god-like on your quest to rid the world of Dracula's evil. Nocturne, by and large, plays like the original Symphony. Unfortunately, the Saturn port has some serious issues, preventing this 'enhanced' edition from being the definiative release of the game. Referred to as Nocturne in the Moonlight in the States ( Nocturne in the Moonlight is actually the name for Symphony in Japan - calling the Saturn port Nocturne is an easy way for American audiences to differentiate the two), the Sega Saturn ports adds in a bonus playable character, two new areas to explore, and (since it was a Japanese-only release) the items that were removed from the American release were left in. In Japan, some of these issues were 'corrected' with a Saturn port of Symphony. There was the expected translation from Japanese to English, but also a couple of 'important' items were removed (although they were rather duplicative of items left in the game), and certain features that were probably planned for both releases (US and Japan) were scrapped. When Castlevania: Symphony of the Night was released in the States, it underwent a few changes for American audiences.
