It happened only one time, when playing Final Fantasy X, I really wanted to know what they were saying before finding all the Al Bhed primers. So I found a few NPC, took notepad and using a few letters found in the beginning, I was guessing what they were saying. It was quite satisfying and helpful, albeit easy.
