It’s not that the game companies are unwilling, it’s Apple that isn’t.
The earliest computer games were released on Apple personal PCs. Many of the pioneering and landmark games were released on the Mac. For example, Microsoft's famous Flight Simulator and Halo series were first launched on Apple's original 2nd generation machine. There was an episode at that time when the developers of Halo made a shooting game called "Marathon" (the predecessor of Halo) and wanted to release it on iMac. Jobs saw it and thought the game was great, so he immediately agreed. Bill Gates from Microsoft also took a fancy to this game, but he bought the studio directly and gave them an office building.
At that time, Apple computers had always been positioned as office design and high-end, and were unwilling to lower their high prices. Jobs also wanted to give Apple computers more gaming opportunities, but the board of directors disagreed. Those capitalists only regarded computers as commodities and did not want to develop them into entertainment. So for things like acquiring a game studio and directly delivering the building, Jobs himself couldn't make the decision. So Jobs later became frustrated and left Apple. The establishment of Pixar Animation Company and his return to Apple came later. After 1995, in order to let thousands of households use its system, Microsoft not only sold it at a bargain price, but also developed the great software DirectX!
Now back to your question, why is Apple unwilling to win over more game developers? In fact, after Cook took charge, Apple has never given up on the development and operation of games, like many 3A mobile games. Products exclusive to Apple, such as Sword of Excellence, Fortnite, Vainglory, etc., are all given priority to be put on the shelves at the Apple press conference. Cook does not have any ideas about PC games, which also shows that he is very far-sighted. The PC market has long been a sunset industry. Just look at the current income of major domestic game companies. Mobile games have already accounted for more than half of the country, and even major companies are unwilling to produce client games. The cost of adaptation and subsequent optimization for client games far exceeds that of mobile games. Mobile cloud platforms are the trend in the future.
Whether the powerful performance of Apple m1 is good for playing games? The answer is no. Don’t take the running scores of m1 so seriously. In the final analysis, you still don’t understand the meaning of the ARM architecture. It is simply not common sense to think that a CPU the size of a fingernail can defeat a CPU the size of a palm with extremely low power consumption.
It is an indisputable fact that Microsoft systems now monopolize more than 80% of the market. There are still some cross-patents between Microsoft and Apple. Jobs and Bill Gates were also close friends. When Apple was about to collapse, it was Bill Gates who invested in Apple and took back some of Apple's shares to help Jobs regain the CEO position. But no matter what, there are no permanent friends in the market. They are still competitors. In such a PC monopoly environment, why should Apple let go of its 30% share of the IOS market to grab the leftovers of win?
