What I want is, ideally, a game client (supported by a web service) that acts as a unified game library, friends list, and achievements list, tracks what I play (no matter where that game came from nor what device I am playing it on--PC, Xbox, etc.), allows me to rate what I play (maybe from 1-5 stars), acts as a social hub for my games (with posts from developers and other players), and makes personalized recommendations. Its recommendations should start with games I already own or have access to via subscription, and haven't played yet but would probably enjoy, based on my preferences; and then after listing those games, it should list games that I don't have and would probably like, based on my preferences, and it should show me prices at various stores for those games.

It would also serve as a searchable and browsable database of games, and GOG Galaxy 2.0 already serves as that because it implements IGDB. What IGDB and GOG Galaxy 2.0 don't do is include on each game's page technical details about each game, such as sound (mono sound, stereo sound, Creative EAX, 5.1, 7.1, etc.). I have posted a request on IGDB's forums to add technical details to each game's page, and if IGDB follows through with that request, then GOG should implement that new feature from IGDB.

Moby Games, another game database, offers on each of its game pages technical details like those, and if Moby Games offers a public API, then GOG should implement that API, until IGDB offers better technical details.

The GOG Galaxy game client would have a web site equivalent, optimized for mobile devices. The web version wouldn't be able to launch games, but it would be able to do everything else that I said, because the features that I mentioned, and the integrations that would be required with other stores, would be implemented on the back end, not client-side. With GOG Galaxy 2.0, integrations are only implemented client-side.

I have yet to find such a service.

I might even be willing to pay a small subscription fee for a service like that, depending upon the cost. Perhaps $1 per month.

There are other web services that do some of the functions I described, and maybe GOG could implement their APIs or scrape their pages. For example, If IGDB implemented a game recommendation algorithm with public APIs, then GOG could simply implement those APIs.

For me, the features and ideas that I listed above are more important than DRM-free games. DRM-free games are nice, but they're not the primary reason that I use GOG and GOG Galaxy. I love that GOG Galaxy 2.0 syncs my games across all of the different game sources that I have, and now I'm looking at ways to find new games, and personalized recommendations would be one of them. Still, as for DRM, I hope that GOG continues to pursue DRM-free games. I don't currently need to be able to play games offline, because I am online all of the time, but if I want to buy an old game that doesn't work well on the current version of Windows 10, and only works well on an old version of Windows that is no longer receiving security updates, then I'll want to install that version of Windows (or a suitable similar version) on a separate PC or virtual machine, and keep that PC or virtual machine offline to keep it secure.

I don't know anything about this issue with GOG and China, and I'll look into it. GOG better not be censoring content outside of China according to China's rules.

Some people spend way too much time on forums. I don't think they even play videogames.

That's you. You can find your DRMed games numerous other places. Try them. DRM-free gaming is the raison d'etre for GOG. You list plenty of nice haves, but nothing you can't easily get just by using existing other sites and then searching to buy on whatever anti-consumer DRMed cesspool you'll rent games from.

Galaxy 2 already has too much shit that's causing GOG to neglect its existing site and offerings... And I REALLY hate DRM and microtransaction shit being advertised to me by it, so, no. You're asking for anti-features there with most of it.

Let me give you a metaphor:
You just walked into McDonald's and said, "I'd like you to start selling gourmet bread bowls and focus your core business on bread and soup. I'd also like the menu for TGI Friday's, please."

You're doing it wrong then.

The problem is:-

1. No store wants to link to its competitors so you are no more going to see a price comparison list for Steam, GreenMan, 101 other cheap key resellers, etc, inside Galaxy's checkout page for the same reason you don't see "Buy now on GOG!" inside Steam's. Sites like isthereanydeal.com will remain 3rd party for this reason.

2. GOG are a small store with limited resources. They aren't going to create a "web site equivalent of GOG Galaxy game client especially for mobile devices" just for a few GOG users to lookup metadata on in addition to the client / website. And it's enough of a challenge keeping them focussed on core stuff (like game updates) without more distractions.

3. Nearly everything you want (always online, "I'm happy to pay a subscription fee for GOG to turn their client into a service", etc) is better provided by an always online DRM'd service that's the exact opposite of what GOG is. You say "DRM-Free is unimportant" to you, yet it's DRM that locks you into using certain compulsory clients that you complain lack features. Imagine if all games on Steam, Epic, uPlay, Origin, etc, were DRM-Free. It would be far more likely that 3rd party custom launchers like PlayNite (that does have igdb.org integration, etc) would be significantly more advanced than they are if they weren't held back by store-front DRM tribalism.

The best game client is a no game client.
