That's so false.. That's like saying the only games Windows can run is Halo and whatever crap is in the Windows Store. Steam has thousands of out-of-the-box compatible games and Crossover helps cover many other games.

Before I got I rebuild my Linux gaming PC (watercooling shenanigans) I gamed for a solid year on MacOS. I played Baldur's Gate 3 on release for Windows through Crossover, was on my second play through when official Mac support dropped. I've played Civ 5 & 6 with friends. I've made many cities in Cities Skylines. I played FF7 Remake again. Even for old 32-bit Windows games like Touhou 6 run with minor tweaking.
