LurkerLito: Personally and I am sure this isn't going to be a popular opinion, but I don't think it will ever be released here on GoG. Sony wants to expand their games to link to PSN for more control (ie DRM and tracking of how you play etc...). They already willingly killed sales of Helldivers II and Ghost of Tsushima in other territories that probably combined equal the sales GoG generates for them when compared to Steam. So I don't think we will see anymore PS games on GoG. What we have now is all we will get. I mean just look at the evidence, we still haven't gotten Ratchet and Clank A Rift Apart and that is a few years old now. We still don't have Horizon Forbidden West yet either that was released like 5 months ago (remember HZD was released 3 months after the steam release) and those two don't use any PSN stuff at all. Sony doesn't care about GoG because GoG isn't generating them sales even close to Steam, and for a GoG release they have to give up their control of the product features they want most, data gathering on you.

sfonor: WHEN Ragnarok on GOG?

It makes no sense to buy just the first game.

JamesBond007: I have some good news.

According to this IGN article, Sony is going to remove PSN account requirement from some of its games, including Ragnarok. However, linking an account will give you some bonuses. In Ragnarok's case, it will be Armor of the Black Bear, which is normally available only during New Game+.

So there is still hope for Ragnarok on GOG in the future.
