I want to play this game on Geforce Now but it seems GOG is not supported platform. Any chance you will implement this guys? Thanks

Came here to ask the same. But sadly GOG seems to be completely unwilling or incapable to release anything but CDPR games on GFN. No idea why that is.

I got the Control Ultimate Edition on a discount, that's why I own it on GOG. But generally speaking: Do not buy anything on GOG that you want to play through GFN. Just stick to "good old games" here and buy the newer stuff on steam.

Until now there is no way, but maybe we can change that. I added a request for exacily that in the features wishlist. Feel free to support that wish. Maybe they just don't know that we might want that.

GOG games are NOT on GeForce Now, not even CDPR games.

Steam Library games can't be played on GeForce Now either (they could during the Beta), because AAA publishers blocked it when Nvidia tried to take the piss, Steam doesn't own the rights, and neither does GOG. Why do you people think Control, which is published by 505 Games, is anything to do with GOG, outside the GOG store.
Only the games Publisher gets to decide where you can buy the game.
It's same with setting the price of games on GOG (Sales included), they are ALL set by the Publisher of the game, NOT GOG.
GOG runs the sales, but Publishers choose if a game joins the sale, and what the discount is.
