The problem with video games is that publishers want to get on as many platforms as they can, so they have no loyalty to any specific hardware platform, which goes against Apple’s entire modus operandi - Apple wants its 3rd party developers making things only for Apple platforms, so that it’ll be really hard for customers to switch.

The only way to get around that in gaming is to have 1st/2nd party developers (like Nintendo/Sony tend to do), but making games has never been in Apple’s culture. Movies/TV shows are a bit closer to their DNA, and they’ve started producing those with mixed results - games would be a much taller order.
