Silent Hill: Book of Memories to be “canonical”

Recently, when questioned, on Tomm Hulett official blog, if Book of Memories was canonical or not, and if it fits in with the main series, the Silent Hill producer answered:

(…) That said, BoM’s story is canonical.

This means that Book of Memories, despite of being a spin-off when we talk about the gameplay, it still serves the series as a canonical entry, something that most of the fans didn’t expected.
