I covered this. This puts you solidly in the "consumes games at an unusually rapid rate" category.

and if you search for Dust on gOg (https://www.gog.com/en/game/dust_an_elysian_tail), you can see that it is self-published by Humble Heart LLC here, MS has nothing to do with it. Publishers can be limited to certain regions or stores depending on contracts.

Phil Spencer fills his mouth with lies like the fact that he wants to preserve games, but in fact he only promotes his platform and the worst forms of DRM, and his ultimate goal is to spread the Game Pass model with perpetual subscriptions.

The only thing we can hope for is that they leave some freedom to the studios under their control to decide where to release their games, so that for example Bethesda continues to release some games on GOG every few years.

It does not matter, the fact that they changed it from MicroSoft Studios to Xbox Game Studios on Steam, means MicroSoft still publishes it.

Watch whenever MicroSoft is officially announced on gog.com, that gog.com will add the Xbox Game Studios tag to their store, you just watch and see gog.com will do this.

no, it does not autmatically means this. A developer can have different publishers on different stores, and even have a publisher for one store and self-publish on another (CD Red deoes this with the Wicher series, for example, you can see differnt publishers for different stores and medai). It all depends on the contract between the developer and publisher, and you do not know what their contract is.

At the moment, there are no connctiont at all between MS and gOg.

Watch the Microsoft and or MicroSoft Xbox Game Studios tag get added to the gog.com store page of Dust: An Elysian Tale and Psychonauts 2 when MicroSoft officially joins gog.com.

Sorry I mean once MicroSoft officially joins gog.com it will be changed and it will be for both Dust: An Elysian Tale and Psychonauts 2, Psychonauts 2 is already listed as Xbox Game Studios. Is what I meant.

A good example of that is ori and the blind forest. On steam it's published by xbox game studios, and on gog by thq nordic.

and that is a very good point that contradicts your argument. as Xbox Game Studios are already publishing a game here on gOg, there is no reason why they should not be listed as Dust's publisher as well if you are right. The fact that they do not means that you may be wrong here.

if Dust is exclusivly published by MS / XGS, as you claim, then it would be illegal for Humble Hearts to self publish it here.

I also stand corrected, as Psychonauts 2 is published by XGS here, which means there is very weak link, but as far as i can see, this is the only game they have published here.

Lets just go by what MadalinStro says.

Ori and the Blind Forest is a Intellectual Property (IP) owned by MicroSoft that does not have Xbox Game Studios on gog.com, but does on Steam.

how do you know that Ori and the Blind Forest's IP belongs to MS / XGS and not Moon Studios? Being a pubslider does not automatically make you the IP owner . if it was, then Atari, Warner Bros. and Bandai Namco would all own the IP on the Witcher, as they have all been publishers for the different Wicher games... and not CDP Red. This is all dependable on individual contracts. I am not sure you know how this works.

Ori and the Blind Forest is MicroSoft's IP just go read about it google.com it.

While unsure about Ori but right owners of IPs can have the rights split between varies companies or peoples or in cases of ips with different media incarnations only specific parts of the ip rights.. For example here lets take a preime example Marvel comics X-men ip used to be the movie and games rights to the ips was owned by other companies so when higher ups that has the comics rights was like ''if we can't have all the rights for the most profit then no one can '' as the higher ups ordered the people in comics to ruiin and bury the X-men ip as good as they can to screw over the profits in games,tv and movies or so thats the logic being used ..

I bring this up as that could be the situation here rights to Ori , Dust and other ips are quite possible split between enough people that both sides of the argument is correct just that the rights are split enough to allow seperate publishing rights or something

I did, and what i found was "developed by Moon Studios and published by Microsoft Studios."...
Indeed, ownership of an IP can be very complex and convoluted

Read the whole story.

Time line is also very pertinent as the ORI IP (or any part) could be aquired by Microsoft well after the game launched officially. Heck could be aquired mid game development but after the deal with THQ was done, who knows?
Unless we want to go down the rabbit hole and search for the official info or statements, we may not know who, when or % owns the IP and TBH it doesn't even matter.
