To allow for the building of alliances within the game, the app needed a sophisticated chat feature. In the middle of development, Leydon decided it made sense for all players, no matter what their native tongue, to speak the same language. So he built a messaging platform that included a translation engine based not only on Google Translate but also on crowdsourcing. Within Game of War, text messages, comments, and push notifications are translated with about 70 percent accuracy. Log in to the game in Polish, and everything you read from other players is in Polish, too. The game’s players correct any errors they notice in exchange for virtual rewards within the game. From the start, the average player corrected 10 misspellings and slang expressions per day.
