I have to say Clash of Clans is by far one of the most successful mobile games no matter on the App Store and Google Play. That is why plenty of developers including big companies like 2K Games, Gameloft, and Microsoft (Age of Empires: World Domination) were, are and will be copying such type of game.
Today, I have been told a game called World Battle is released for Android that plays similarly to Clash of Clans. In fact, there had been a game called Game of Battles out there that is definitely the same game with World Battle. What is different is World Battle is published by NG Creative and Game of Battles is published by Koolgig Studio.
World Battle (Game of Battles) is a total copy of Clash of Clans. Everything from sound, troops, heroes and structures are copied from Clash of Clans and Boom Beach, just under a modern theme. Such copycat immediately reminds me of GREE’s Call to Arms.
At this moment, the game does not add the clan wars, but if you don’t bother playing a copycat of Clash of Clans, just take a try on this game.
