Yeah, language tables are a given for game series that have been translated into multiple languages.
I love having info on the different names for things in different languages! ...I only know English and Japanese though and I'm sure that's covered by other users very easily. :\
(Not sure how useful a specific language table/template would be on WB though, the Mother series has only ever been in English/Japanese, so.. well, it wouldn't be there, I guess. It definitely comes in handy on other wikis though.)
