Building off of this thread (http://sinisterdesign.net/forum/index.php?topic=1632.0), I decided to make a mod that translates all Lissit text in the campaign. Translated text is demarcated by curly brackets {}.
English sprinkled with Lissit words is kept unchanged (since they're usually obvious from context anyway). And don't worry, I didn't try to localize Silithis' name as "Patience" this time. :p I did take one liberty, which is that I assumed that every cutscene where the lissit talk among themselves is actually in Lissit and translated into English for our benefit; thus, I bracketed those entire conversations, and translated any sprinkled Lissit.
Feedback is appreciated.
And uh... I seem to have gone over the limit for number of attachments per post. I'll continue here, if that's okay...?
Fun fact for you: you can put all of those files into a single .zip file and it will count as only one file! This also makes sense from an ease-of-access perspective, as the user would only need to download 1 file opposed to 10.
