GoG please don't start making exclusivity deals with devs for the storefront. The appeal of being on PC is the freedom of choice. You of all companies should know that, considering you're aware of the freedom to own and do with games as you please that appeals to customers. Its the same garbage Epic does with some PC releases. Games should be on as many stores as possible, ideally.

"maybe they wanted it to be drm free"
Contrary to popular belief it is entirely possible to release a game on Steam for example DRM free. There are DRM free games on Steam; Trails of Cold Steel, for example, does not require using the Steam client at all after you purchase it there.

This is very clearly GoG paying developers for exclusivity rights on the platform, and that's really scummy. GoG is cool. DRM free games are cool. Intentional store exclusivity is not.

PC doesn't have freedom of choice. Either you put your game on Steam, or your game fails, which leads to everyone just putting their games exclusively on Steam anyway, which is bad for competition, like GOG. That sound like people are getting a choice?

Exclusivity is a necessary evil that helps break Steam's (and any platforms) dominance in the PC gaming market. It doesn't help that Steam has way too big of a cult following, who like to go crazy at any kind of "exclusivity" on any platform that's not Steam, while also making excuses for Valve's abhorrent practices like their continued reliance on lootboxes in their games, with no age rating, allowing users under the age of 13 to gamble away their life savings and sell them on third-party sites.

The reason GOG doesn't get as many games as Steam naturally does is literally because of Steam's market dominance, which they obtained by starting out with exclusives, forcing users to make a Steam account.

FYI Steam started and continued to grow because of exclusives and games only releasing on Steam (and now continue to only release exclusively on Steam, due to its market dominance).

There's no freedom of choice. 90% of the market is filled with Steamworks or worse.

Imagine complaining about DRM-free exclusivity...

Another theory to consider is perhaps the developers are fans of GOG and totally agree with GOGs mission and decided to be all into this mission.
