Another milestone for Valve here, as the Steam Deck has now managed to hit the 14,000 mark for games that are rated either Playable or Verified.

Of course there are many non-verified games that run fine as well.

For comparison, the Switch has somewhere between 5,000 and 10,000 games.

Source: Wikipedia lists about 5000, Nintendo says “over 5000”, but this website claims 10,880. Part of why the Moby Games website lists more is because it lists multiple versions of a game as separate games (Xenoblade DE is listed 4 times for example).
