I found such information on the Internet:
Cocos2d-x now has 1.1 million developers, with big games such as Angry Birds, Badlands, Fight !, and Clash of Kings
It's true that more than 1 million developers use the Cocos platform?
This information concerns the Cocos engine.
There are about 24 thousand registered Cocos-BCX developers now and this number continues to increase every day.
