At this year's WWDC 2020, Apple shared details on how gaming will change on its platforms. Some big changes are coming, not in the least as Apple will switch its Mac computers to ARM over the next two years. The center of gravity for gaming on the Mac is moving to mobile and the company will greatly expand input options. Apple's Game Center will also be getting an overhaul.
In a hugely consequential change for the Mac platform, Macs running Apple Silicon will be able to run iOS and iPadOS games. Developers will be able to choose whether their iOS or iPadOS games are listed on the Mac App Store, but if they choose that, the games will run natively, with minimal additional work required.
This is a seismic shift for gaming on the Mac, and it may represent Apple giving up on a strategy that has never really worked that well in the 15 years since Macs moved to Intel CPUs. Mac games have generally been ports of Windows games. Not all games get ported, and those that do often don't perform well.
