Sorry if this has been asked before.
Steam now offers 74 more options (in addition to the existing 28) for you to select from when indicating which languages your game supports.

It is only for indicating game support. In the same web page it explains what should be done to add them.
I would like to see some of these languages added to the Steam Store, as it will also help for the visibility of RimWorld (I think Steam also plans to add a language filter soon).
Is it possible to add the missing languages that have a near complete translation?
