You can see the same game go by three different names on a community forum, Wikipedia, and a catalogue of games + md5sums for a system (you might think the md5sum could act as a Rosetta Stone here… but less so than you’d think, especially in the specific context of an English speaker and Japanese games, as you sometimes need some specific, old, oddball and slightly-broken dump of a game to get the one a particular English patch requires… and god knows what name you’ll find that under, but probably not the same md5sum as a clean dump)
The only bright spot in this is that if you can find a Japanese game on Wikipedia the very first superscript-citation almost always lists the official Japanese title in Japanese script on hover. That’s a life saver. (Presumably all of this is easier if you know at least some Japanese)
Though after I posted my comment I realized they mean they’re switching to another existing system (which I think is already widely used in gaming circles? Not sure though) which isn’t so bad. At least it’s not another one being added to the mix.
Consider 彼氏彼女の事情[1]. The Japanese name is the same for the Manga and Anime, but the official names for the US localization of each are different (the manga went with a romanization of an abbreviation of the Japanese name Kare Kano while the Anime went with a translation of the full name His and Her Circumstances.
Needless to say, the official English translations didn't keep that title, going with "What are you doing at the end of the world? Are you busy? Will you save us?"
