The Steamdeck is a success.

It's not like how Steam machines came around and then imploded... Never to be mentioned again.

It's getting the support, it's getting the sales to justify it's existence.

I wish the number of hours you play a game gets counted when you are offline.

In several fronts it definitely deserves existence. Do we know it’s sales?

'Multiple millions', see https://www.vgchartz.com/article/459011/steam-deck-has-sold-multiple-millions-of-units/

I love how steam is able to move units through their own market chain. I’m sure they increase their profits by selling to their already huge customer base without distributors/marketers costs. So that’s a lot of extra profits in their pockets. So glad they nailed it with a successful product. I’m sure all steam gamers see this as a really good thing. 

Yeah, the effort they have been putting on the Deck is remarkable.

It's a constant chart topper, Valve is planning future upgrades. I imagine it's a success.

It would be nice to know exact numbers, though. It's been almost two years of market presence. Transparency is good.

I was thinking the same. I don’t know how vgc gets its sales numbers. I guess Steam doesn’t need to release them since they aren’t interdependent like other manufacturers. 

Update of previous compatibility results broken down by SteamDB rating (2023-12-03):

A total of 12699 out of 16159 tested Steam games are now rated "playable+".

38.0% of the 1518 "90+ games" and 27.3% of the 4998 "85+ games" are now "verified".
78.0% of the 1518 "90+ games" and 62.3% of the 4998 "85+ games" are now "playable+".

78.6% of the tested games are playable, with tweaks a lot more.

The higher the SteamDB rating, the higher this percentage becomes: at 80+ rating it's 84.1%, at 85+ rating 85.4% and at 90+ rating even 86.9% playable without any tweaks:

51.22% (2695 games) of my own Steam library are now categorized as "verified" or "playable"... a year ago it were only 1639 games.
The majority of the untested 36.68% is probably playable, too.

Only 12.11% of my library is classified as "unsupported" so far; when excluding VR games only 9.77% of my library is "unsupported".

I can look back one year in the CheckMyDeck history. The "Unsupported" percentage has only increased by 7.9% (12.11% / 11.22%) despite thousands more test results, while "verified" has increased by 42.9% (22.52% / 15.76%) and "playable+" by 37.6% (51.22% / 37.22%):

Incidentally, you can use "dynamic collections" in the Steam client to visualize your own steamdeck-compatible games and define the desired sorting. Additional filters (e.g. game genre, store tags) can also be added:

The number of compatible games is even higher here than with CheckMyDeck, as compatible game demos and free games are also included in the Steam client's dynamic collections.
