Recent big multiplayer games:
Marathon, no Linux support.

...and yet out of 280 multiplayer games in my library 200 are marked as Deck Verified or Playable (and most of the rest has no rating available). Also, looks like all of your examples are from a single particular niche.
I like Linux alot.
But if the biggest multiplayer games straight up don't support it, that needs to be acknowledged.
Add League of Legends to the list.
I've had Deck verified games straight up refuse to work on Linux.
