Castlevania is a series with heritage. Since its introduction in 1986 it's rarely skipped a year, with 40 released titles spanning consoles, PCs and arcades. Over nearly 30 years, the backbone remains the same. The plot is an eternal repetition of the need for the Belmont clan (and occasional affiliates) to destroy Dracula who, against all odds, keeps getting resurrected in all manner of bizarre circumstances. Features and details may change, or occasionally be absent, but they're indelible parts of the series, always remembered, always returning.
