Well, it started early in 2014 / 2015 .

Strange.... Started on 4th ended on 15th December and called "2014 drm free big fall sale"

Yep . It was a short sale .

It only happened when the previous sale started\ended earlier tho

Extensive task, but it would be helpful to have a list of all the Winter, Summer, Spring, Halloween, and Biggest Special sales from the start of 2008 till today.

you mean this ?

edited November 21, 2023 He made it! ^ Yes, thank you Both!
edit: I will help to fix a few dates.
Edit 2: for the last 5 years it has been roughly the same pattern, three weeks, over the New Year until 2nd-5th Jan, and two weeks after the previous Big sale.
I bet on 12th December to 2nd Jan : )

in addition found: "From Wishlists, With Love - - - - - 13-20 Feb from 2017", which would indicate someone reading our wishlists, what a heartful idea.

i see

Rawcember Goodie Pack is on giveaway till 13th (Wednesday) which is sort of unusual, so I'd bet it'll be that day or 14th.

Another herald of major sales has arrived - the price matrix has been updated.

For the few games that aren't regionally priced, local currency values are slightly different.

AUD priced products are now cheaper, which is a pity. For those with 0% currency conversion credit cards, unfair exchange rates actually result in cheaper products if you pay in USD. (Regionally priced items are fixed in the local currency, the USD value floats with the exchange rate).

JFI: After claiming the gift don't forget to go to your profile settings and deactivate marketing communications subscription, like always when GOG gifts you something on the front page.
