Music might be the industry with the most ridiculous amount of genres and subgenres, but gaming can't be far behind. It used to be simple: sports games, adventure games, space combat. Then came the Roguelikes, multiple varieties of shooter, and suddenly we have mouthfuls like Metroidvania and MMORPG.
The fragmentation has only intensified under the influence of digital algorithms. Meanwhile, a constant blending of styles has resulted in increasingly niche micro-genres (dating sim horrors?)
