The setting I DM, like a lot of fantasy and sci-fi settings, has a vast
array of languages spoken by a vast array of people. I often find myself
wishing that I didn't need to skulk around and whisper translations to
my players over skype or PMs. What would be cool is if we could assign
languages to character sheets, and any player who controls a character
can use a command or macro of some sort to "speak" in a certain
language, muddling it or rendering it gibberish to any players who don't
have a character that speaks it. I feel like it would both
make things easier for DMs and also encourage roleplaying. Too often, I
find my players saying "I relay that to the group," when I'd like for
them to actually think about how their characters would say something.
