Captain_Shiny: Oops, sry about that headline - "most big sales" was how I intentionally phrased it in the text itself cause I noticed that it's certainly not true for all sales big or small. I didn't give much thought to the headline tbh. Anyway, I assume that it's most or many big sales. I don't have concrete evidence other than my memory, though and that might play tricks on me but I'm rather convinced that "many" is at least a fitting qualifier. I also include Steam sales for that, btw.
skeletonbow: Ah, I've never had that impression myself, but I had a look only at GOG's major promotions over the last 4 years and they are rather equally scattered with no seeming pattern in terms of offset into the month. Not sure about Steam or other stores sales as I haven't looked at that but I have observed that GOG sales often seem to precede Steam sales as if GOG knowingly plans their promotions ahead of Steam to drain people's wallets while they still have money in them perhaps. Not sure how closely that follows through over time, but I've noted it many times at least.
What would be interesting, would be some kind of web based sale analyzer that predicted when each store's next major sale would be based on prior sales date data. :)
Yeah! That would be pretty sweet. It would make (videogame)life a lot easier if I knew when to set aside some money for an upcoming sale. Apart from the really big seasonal sales of course - those are a given by now.
