I would say Counter-Strike (especially GO with it's matchmaking) is a good example of a successful international game. It was not uncommon to have Chinese, Russians, Japanese, Koreans, etc. on the same server. A lot of people have learned a few words from other languages like "thanks" or "fuck you". There is some basic coordination of tactics too because the goals in the game are "A" and "B", or asking a teammate to buy a weapon for you, a "drop".
