Microsofts policy is exactly the same as Steams, Sony allow refunds within 14 days but not if you downloaded the game. UPlay/Sony need to catch up and add either the under 2 hours played, or the within 24 hours of first use policy that the others use. Nintendo are the worst of all and don't even do that.

Good

Steam - Refund any game within 2 weeks of purchase and under 2 hours played.
Origin - Refund any game within 24 hours of first launch or within 2 weeks of purchase.
Epic Game Store - Refund any game within 2 weeks of purchase and under 2 hours played.
Microsoft - Refund any game within 2 weeks of purchase and under 2 hours played.
GOG - full refund up to 30 days after purchasing a product, even if you downloaded, launched, and played it.
Stadia - You can request a refund within 14 days of your purchase if there is less than 2 hours of play time

Bad

Uplay - Refund within 2 weeks if game not accessed.
Sony - Refund within 2 weeks if game not accessed.

Terrible

Nintendo - "We are unable to provide refunds or exchanges for mistaken purchases, and/or if you don't like the game."

Uplay Sony and Nintendo need to sort their shit out.

Especially given that Sony will run into problems with this if people but their DIGITAL ONLY PS5, that's just asking for issues.

Woah! Thanks for the info dump. I don't know why, but I'm honestly surprised that Microsoft and EA have parity with Steam on this front. The way you described GoG though sounds almost too good to be true. Is it really "no questions asked" for those 30 days? What if you finished the entire game in that time?

It seems once you've played the game GoG's refund only applies if the game is broken and doesn't work, so it's not as great as it first appears.

If you've not downloaded or played the game you can get a refund no questions asked.

If you have downloaded and played the game then you will only be refunded if tech support cannot get the game to work on your system.

"At GOG.COM, we're confident in the quality of the games we sell and the work that we put into getting them ready for you to play them. If a game that you've bought on GOG.COM doesn't work and our team of expert Support staff can't solve the problem for you, we will give you back your money. If you absolutely refuse to try anything, we won't be able to determine whether the problem can be fixed or not, and won't be able to issue a refund."

The tone of your post just became the kettle. So whatevs man.

Expected again. Because I point out the poor responses the OP got, and instead of looking at yourself with introspection, and realize the responses he got were unwarranted and unnecessary harsh and made to ridicule him, you try to mirror it back at me... 

The two aren’t even close to being the same. But nice try, I guess.

That awkward moment when someone who has a history of unwarranted responses, such as calling people out for uttering a certain R word and Xenoblade in the same sentence when it has no relation to the actual topic, wants to complain about people having toxic and unwarranted responses.

All stirring the pot does, is cause more toxinity withing the subject.  Let it go.
