Here's a list of all the Apple Arcade games on PC

There are already plenty of Apple Arcade games on PC. The library boasts a wide variety of hand-picked games that you can access through its subscription service. While the roaster of games features games from the likes of SEGA, Cartoon Network, and the Lego games, the service also has a bunch of indie studios like Finji, Annapurna Interactive, Gian Squid, ustwo games, and more.
Many of the games in Apple Arcade are strictly available on the subscription service only, but many have made their way to PC after a short time in the arcade. Similar to the Epic Store's exclusivity, some of the games in the arcade are exclusive to Apple for a short period of time, but unlike Epic's standard year wait, Apple Arcade's time period can vary.

Most of the games released on both PC and through Apple Arcade have around a month or two of a waiting period. Take Simogo's Sayonara Wild Hearts as an example. That released on Apple Arcade on October 8 then made its way to Steam on December 12.
