I'm lazy, so I do the same. I use titleText rather than make the apropriate stringtable. But there is one minor problem with this technique. LetÂ's say you have a script that includes the line
speaker say "myOwnVoiceIsBeautiful"
titleText ["Whatever the subtitles should be", etc]
That sounds fine as long as speaker is alive. If speaker is dead, no sound will be heard, wich is also fine (I don't like the speaking dead ;D )
But the titleText will still be displayed in this example. I think that if you make a stringtable, it's linked to the actual sound file. Hence: No sound - No subtitles.
I had this problem when I was working with my campaign Finlndsky Vokzal. It's quite easy to include the condition alive speaker to the script. But with stringtables you don't have to do this, as far as I understand. Am I right or wrong gentlemen? I' not completely sure.
