The campaign I currently DM uses English for Common, German for Dwarvish and Japanese for Elvish.
The setting's background is that the players (all human) emigrated from an "old world" continent, where a human (lawful) theocracy has been conquering and enslaving the local dwarves. The "new world" they wind up in is populated by elves and orcs, with a few recent settlements of human religious (good) emigrees springing up. The theme is very much exploration of a new continent, with conflicts arising from it's dark history and the clash of human/elvish cultures.
My players are all German, but we play in English. Since by design none of the characters in game knows Elvish and I'm the only one who speaks Japanese, it works really well to illustrate the different cultures and lend the "new world" an exotic flair.
