Just did a GOG survey that focused on the idea of a paid membership option on GOG. Seems they're determining what people would be willing to pay extra for. Some of the options were
- a tool for backing up offline installers
- ability to install previous versions of a game
- extra insight into the preservation work they're doing.
- voting rights on games to bring into the preservation program.
And others that I can't remember.
Does God of War count?
I know it came to pc as a whole but it’s available on GoG as well
God of War came to Steam first, it wasn't because of GOG efforts. The games that GOG manage to bring back (RE games and Dino Crisis for exemple) had japanese PC clients.
Pretty sure it released on both platforms at the same time, as far as I’m concerned any games that show up on GoG with no DRM take a bit of effort from GoG to actually verify and host the installers, more so when the contracts expire and they have to delist them and try to get them back
Yes GOG takes a bit more time to verify the installer, but I'm sure when Sony put the games on PC the reason was the massive Steam (and maybe Epic) userbase, GOG was an afterthought.
