Taking into account the constant growth of this market, it can be said that competition on it is less than in other areas as the size of the pie is constantly increasing.
It seems that before choosing a market segment for the implementation of this project, the developers conducted a serious analysis of the market and chose the most promising direction.
I can assume that the core of the team consists of game developers, after they decided to do their own project, it remains for them to choose the most profitable direction of implementation.
