It's interesting to think about gaming specifically. Genuine platform exclusivity is rarer and rarer these days, as the underlying engine market has become more and more commoditised. It is relatively cheap to port a game built in Unity or Unreal engine from PC to Xbox, PlayStation, etc. Mac has always lagged because the market wasn't big enough to warrant investment. Catalina wouldn't have cratered your gaming library if there was enough incentive for the developers to update the game. Now that iOS apps (read: games) can run on Mac with relatively low effort, and we already see PC games being easily ported to iOS (eg: Fortnite, legal challenges notwithstanding), I feel that this is the best thing to happen to Mac gaming in years.
