Except for games with anti cheats, can you quote from your head three games the last 10-15 years that aren’t running perfectly on Linux ?

Because from my ~1 500 titles steam library, I can think of one game that I had issues with. And even this particular game (which is Tomb Raider 2013, btw) worked perfectly fine after a little hack. And ironically the "hack" was checking a checkbox in Steam to force using the Windows version of the game instead of the official Linux port.
