The next time you find yourself sitting down with your friends to play a game of Ocean, consider employing this little twist: None of your characters can verbally communicate.
For whatever reasons, your characters cannot effectively communicate with written or spoken words. Everything they try to say or write comes out as unintelligible, indecipherable gibberish. Nor can players directly tell other players the ideas that their characters are trying to impart upon one another. Instead, players must communicate in the game only through actual descriptions of what is happening. They can explain what their character is doing and the actions their character is taking to communicate, but never can they directly relate why they are doing what they are doing.
I want to give this a try at a Convention some time.
