Might & Magic Heroes: Era of Chaos
Mobile game by Ubisoft, with inherited some sources and heroes from Might and Magic Heroes III Universe. First popularized in China in 2017, then Philippines and New Zealand, with the last stance being the rest of the world. Graphic style is simplified anime. Expected audience seems like younger players.
Decisive factor here are unit formations, and levelling. Game has semi-automatted grinding.
