Makes sense since 2D Castlevania was most popular on Nintendo (with SotN exception). If it was 3D hack and slash or GoW style like Lament of Innocence, Curse of Darkness, or Lords of Shadow, Playstation and Xbox would've sold better.
Shame that the go to console is the worst version. And the review embargo hurt the game imo. Haven't seen near as many people talk about Bloodstained as it deserves (especially considering it's one of the few good high-profile Kickstarter games). The world deserves more games of this genre/caliber since Konami seems content to at best, make rereleases.
