This game is not invalid because the DOS version of the game was
released in the United Kingdom, a country whose primary language is English.
Also, the game is no longer supported, the game isn't sold anywhere, the developer is not ESA-protected, and although the publisher is protected by the ESA, the game is no longer protected by the ESA since 2008 (1997 + 1 year due to no solid release date + 10 years ESA protection = 2008). Unless a valid buylink can be found, this game is approved!
