I just realized every game in the Darksiders series is a different genre

Darksiders 1 is a hack and slash inspired by God of War and Zelda, Darksiders 2 is a looter rpg, Darksiders 3 is a soulslike, and Darksiders Genesis is a top down isometric co-op game. Based on the previous games, I actually have no idea what genre and gameplay Darksiders 4 will have. I dont know if this has ever happened in a series with multiple mainline numbered games before or is Darksiders the only one?
