Although this is an interesting suggestion, I think one of the reasons that you have to declare what languages your game is available in, is so users can search for games in a selected language. Which means that it’s unlikely for a user to search for a custom language.
The only scenario where this can be useful, is when a user is reading details of your game, in which case you can mention it in the game’s page that your project supports custom languages.
It's not that unlikely, comunities based around conlangs would do that a lot, just to find media related to their community. One of the reasons I have the option to put my game in toki pona is to bring a bit more content to the community, but then the question is about how would they find it, which is why I made this thread in the first place
Still I’m not sure putting it as a language is the best choice. How about adding it as a tag in the game, that way users can search by tag? They are meant as “custom keywords” for when users are searching for new games.
Apologies but I’m not familiar with “toki pona” or any community for custom languages.
I’m more familiar with Dungeons and dragons languages, like elvish, but I see what you mean. I just never thought someone would like to play a game in a language like that, which I find pretty interesting.
Now that you mention it that way, I see why that would be useful for some users. I hope tags can solve it, at least temporarily.
