When we talk nuances, they have control over both up to a certain extent. An extent we know is limited by the number of opportunities from AA and AAA devpubs because their and their investors' skepticism. But to say they have zero control over what they have in their store is quite erroneous.

I can at least say for the JRPG side that I'm still disappointed in what they have. It's even a miracle we have Nihon Falcom, CH/IF, Sega's Yakuza series, etc. here, but there's a lot left to be desired. There's the remaining catalogue that's missing here from their current partner publishers
from the Completionists' List of Missing Games from GOG Series:
- Capcom - everything
- DANGEN - Hunt the Night, Abomi Nation, Disc Creatures, etc.
- Ghostlight - Omega Quintet, Lost Dimiension, Mugen Souls series, etc.
- NISA - Disgaea series, Rhapsody series, Labyrinth of series, Langrisser series, Yomawari, Kamiwaza, ZHP, Makai Kingdom, Monark, Soul Nomad, Legend of Legacy HD Remastered, Crymachina, Phantom Brave, etc.
- Playism - Phantom Rose 2, One Way Heroics, Artifact Adventure series, LiEat, Helen's Mysterious Castle, The Use of Life, Potato Flowers in Full Bloom, etc.
- Sega - everything
- Toby Fox - Deltarune series
- Ubisoft - Child of Light
- XSEED - No More Heroes series, Rune Factory series, Fate series, Touhou series, Senran Kagura series, Sakuna, Cuisineer, Silent Hope, Loop8, etc.
- Zeboys/Shadow Layer - Cthulhu Saves the World, This Way Madness Lies, Breath of Death VII
If GOG isn't doing it by now, they should be curating devpubs themselves rather than the games. And once devpubs are greenlit, they can have a blank cheque to publish anything even if some of them are universally panned games. Because I'd rather have their whole catalogue on here than this seemingly random limited selection of somewhat good titles.
Then there's the matter of other notable indie JRPGs that should be on here, but aren't:
- Sea of Stars, WitchSpring R, Troubleshooter: Abandoned Children, Grey Heritage, Shadows of Adam, The Amber Throne, Jimmy and the Pulsating Mass, For a Vast Future, Cassette Beasts, Omori, etc.
