There are over 3200 games for the #PS4, and nearly 600 for the #PS5. 4000 games playable on the PS5, plus the PSN games.

The #Xbox Series X has nearly 400 games natively, plus 3000 or so Xbox One games, 630 Xbox 360 games, and 63 Xbox games. Let's say 4100 or so games playable on the Xbox Series X, plus whatever the Xbox GamePass service provides.

#SteamDeck has 8000 playable or verified #games, plus an indeterminate number of untested games that probably work.

And because it always comes up, and I ran out of characters in that first post - the #NintendoSwitch has nearly 4500 games.
@AndySocial Wow, this does a good job of putting the numbers in perspective.
@shaneqi As I fell down the rabbit hole, I was surprised to see how few games were available on some classic systems. The granddady Atari 2600 only had around 500 games total.
@AndySocial I sure was surprised. Especially the fact that #SteamDeck’s playable games are double the amount of Xbox or Play Station, brilliant research.
