Clash of royalty or the glory of the king, which is played by more people in the world?

This depends on whether you are talking about a large scale or a large number of people. Clash royale is more famous abroad than at home, but not abroad in the glory of the king. You can only play similar games. Clash royale is big on a larger scale, but because of China's large population base, even if only China people play it, the result is self-evident.
