UPDATE (November 17, 2019): An eagle-eyed fan has noted that the game’s page on the Australian Classification Board website has been made private. This does not mean that the page has been deleted; rather, it means that it is not accessible by the general public.
The Australian Classification Board has classified “Steins;Gate; My Darling’s Embrace” (also commonly known as “Steins;Gate: Darling of Loving Vows”) for release under English publisher Spike Chunsoft. This is likely an indication that the game will soon be released for the west. An official announcement for this title has not been made yet.
Like Europe’s PEGI system and the US’s ESRB system, the Australian Classification Board is an Australian-based government organization responsible for rating and classifying games, movies, and books in Australia.
