I am trying to make an ideological heir to Game Dev Tycoon on C # and started with the development of a prototype game and immediately ran into a problem, for the implementation of the basic processes, it is required that when a user releases a game, it is compared in a rating for example for week sales with the rest of the games released, but how to write an algorithm that imitates roughly the gaming market, which at certain intervals releases games with any genre, theme, rating, sets new popular genres, etc.
How can I implement a simple AI or some sort of similarity?
