It would be the cherry on top if they adapted Castlevania into a game that’s not Castlevania.
Netflix has already gotten into the game space with the licensing of Stranger Things for a couple of games, one of which being by the ill-fated Telltale. But they have more game-related plans for their other originals. Or at least, that’s suggested by their planned panel at E3
As for what, exactly, they might be announcing game adaptations of is really just speculation at this point. Obviously, there’s going to be some news of the planned Stranger Things game, which they’ve pressed on with despite Telltale’s collapse. As for anything else, though, that might be easier to narrow down. The NX account that tweeted the suggested name above tends to handle Netflix’s animated material; She-Ra, The Dragon Prince, Voltron and the like, as well as live-action shows like Umbrella Academy. So it wouldn’t be hard to imagine one or several of those getting an adaptation.
