Currently looking at the top 20 Steam games [0] for today, excluding non-games like Wallpaper Engine. 8 out of 20 work on Mac natively. Out of the remaining 12, 3 of them work with Crossover, so that makes it 11 out of 20. Almost all of the remaining 9 are competitive FPS games that don't work due to their kernel-level anticheat, almost all of which AFAIK won't work on Linux for the same reason.
