Today I saw the GOG Galaxy client featured in the Epic Games client.
You activate it (for free) and apparently you can then install it and run it through the Epic Games client.

What I can't understand is the "Why?"
What advantage (if any) does loading a client from within another client have over simply running both clients independently?

From my experience, if I run a non-GOG game using Galaxy, said game loads through its' native client (Steam for steam-games, Ubisoft Connect for Ubisoft-games etc etc).

Thanks!

I got Gog Galaxy via epic games as well, I previously had it installed but my harddrive ate itself, so it seemed like an easier way to install

Haven't received any games, i do note that it does say on the GOG Galaxy listing in Epic games

so perhaps they havent launched yet?, I'm hoping for an email

Ok, i didn't know about that at all, so I decided to give a look at the Epic Games catalog and it popped out

Nice spoiler of the next freebie tho.

Yes, the games are available from GOG's own page. I actually redeemed the first game (Genesis Alpha One) without installing the "Epic Galaxy" so I do not think installing it is a requirement.

So has anyone found any reason to install Galaxy from within Epic?

It's just a mirror for the client, I think there is no difference between the two, only more visibility for GOG. This happened also for discord, which is available to download on the Epic client.

The Itch.io client is also available to download directly from Epic.

There's really no particular reason to get something from one source or the other.

It's just a current industry trend to make your product into a generic "app store" like platform where you can even obtain/connect other unrelated products (e.g. like how the Windows 11 is taking a MS App Store first approach, or how Microsoft "cloud" products are essentially barebone products that work as storefronts for 3rd party services).

It's similar to how every video content producer / TV channel wants to make their own streaming channels, how every triple a game publisher turns their games into a storefront for cosmetics and DLC.
