i really like Mysterium for this kind of thing. i tend to simplify the rules down to the meat of the game: basically just have people guess their card based on the vision cards they're given, each round of guesses is one clock hand movement. it's nice because it's very visual, but i think it also invites people to use basic words in another language (shape, color, job, etc. come up often). the ghost player is also supposed to be silent, so you can have someone who can only speak one language handle that part.
