Castlevania Advance Collection includes three legendary Castlevania games that were first released in the early 2000s: Circle of the Moon, Aria of Sorrow, and Harmony of Dissonance. In addition, this collection also includes Castlevania: Dracula X and some never-before-seen sketches and artwork from the games! All four games are enhanced with newly added modern features such as Rewind, Save/Load, and Replay, making this the best way possible to experience these classics or discover them for the first time! This collection also boasts a handy Encyclopedia, a Music Player with all soundtracks; and you can even change the ROM Region to play all games in different versions.
