I don't think anyone at Konami way back in 1986 could've ever foreseen the impact that Castlevania would have. Combined with Metroid it spawned a whole genre of games, and without it we wouldn't have stone-cold classics like Hollow Knight, Dead Cells, Ori and the Blind Forest, or Axiom Verge. The Castlevania Anniversary Collection launched back in 2019 to give fans a taste of the early days for the series, and now it's free to keep, giving you eight games for the grand price of nothing.
