The board lists the package as being rated MA 15+, the same rating as the original game.
Such a collection would presumably include Dishonored and the downloadable expansions that have been released for it: Dunwall City Trials, which launched last December; The Knife of Dunwall, which came out this past April; and The Brigmore Witches, which will be released Aug. 13. You can check out our hands-on preview of The Brigmore Witches from QuakeCon 2013 here.
The classification board's listing does not specify platforms except to say that the purported Game of the Year Edition would be a multiplatform title; Dishonored launched last October on Windows PC, Xbox 360 and PlayStation 3.
This is a common practice for publisher Bethesda Softworks, which has bundled add-on expansions into Game of the Year Editions for well-received games such as Fallout 3, Fallout: New Vegas and The Elder Scrolls 5: Skyrim.
