Castlevania Advance Collection rated on the Australian Classification Board
The Australian Classification Board has posted a new rating for Castlevania Advance Collection, registered by Konami on June 18. The registration lists M2 as the author, well-known for classic game ports and who previously worked on 2019's Castlevania Anniversary Collection.
The title seems to imply this collection would be made of the three Castlevania titles that made their way to Game Boy Advance between 2001 and 2003: Circle of the Moon, Harmony of Dissonance, and Aria of Sorrow, though this is of course not yet announced.
Three Castlevania titles also made their way to Nintendo DS in the years after the GBA's lifetime: Dawn of Sorrow, Portrait of Ruin, and Order of Ecclesia. We have little to go on except for speculation at the moment, but if we're lucky, perhaps such a collection would include these games in addition to the GBA titles.
The registration on the classification board is for multiple platforms, and it's worth noting that the Castlevania Anniversary Collection, which included 8 titles, released for PlayStation 4, Xbox One, Steam, and Nintendo Switch.
We'll have to wait to see more details if an official announcement is around the corner.
