There is not a single ways Apple can break into gaming.
Infracstructure is thing to consider, Apple don't have that.
Sony and Nintendo has big infracstructure to be console manufacturers. It is now much harder to get inside. Companies like Sony and Nintendo are too big too fail in the console gaming spaces. Nintendo got big franchieses like Mario, Pokemon and Sony got great tech, services, marketing, studios behind them.
Also same reasons why Sony haven't really moved into streaming services for TV and movies, since they don't got AT&T, Discorvery, Disney, Apple, Netflix type of infracstructure to support, they do have Aniplex though if it counts.
Same for music, second biggest record holders, still Apple Music, Spotify Youtube Music are the biggest and hard to break into. Spotify is the innovator, Apple Music has iOS platform and Google has Android and Youtube.
In reality Apple cannot break into console gaming, as long as Sony and Nintendo still doing great.
