Just look at this.

Give Gog time and they will fix it.

Purchase reinforcement.

Ads for cars aren't really for potential buyers so much as the people who already bought them. Seeing the ads makes them appear desirable and gives you more satisfaction in owning them, which makes you feel good about your old purchases and inclines you to repurchase the items.

It reduces what is called post-purchase dissonance and supports post-purchase reinforcement.

Interesting theory. It might even work for cars, given that (new) cars are such a large investment the average person has to think hard about and justify. It's also no surprise that people get sentimental about their cars, which they own and use for years.

I'm not sure it works for video games which cost less than a pizza and which even a relatively poor person can easily have hundreds of.

The other problem with this theory is that I don't really have post-purchase dissonance about games I got for a dime on some big sale three years ago. I don't think most people would have it.

because recommendations are bit hard-coded

Well, if this would be true, then why are they sending me ads for cars that I didn't buy?
If I go to my car dealer and buy new car "model A", the very next week I find a high glossy brochure in my mail, that wants to sell me new car "model B, C and D", who are bigger, faster and better equipped than that lousy "model A", that I just bought.

Doesn't exactly upping the satisfaction after my recent purchase.
And supporting me in my decision?
By letting the cars that I didnt buy dangle in front of my nose, like you'd do with a carrot and a mule?
Look what we got here...want this, hm? Want this? Come and get it...

Nah, I don't think so.
:o)

That is a cute bunny though.

little rabbit, fluffy bunny
Cute, cute, cute

Beware of the killer rabbit:

I believe those recommendations are more of the "People who bought this item also bought these ones" and not "According to your previous purchases, you will probably like these". So based on the game, not the user.

"Games so nice, you'll buy them twice!"

Actually I am a time traveler coming from the future and I can confirm they still havent fixed a thing after all these years.

I have a million questions about the future but I doubt you could answer,one.

I think you're mistaking the intent. Note the wording: "You may like these products". Clearly, it is meant as permission: "You are allowed to like these products."
By extension, that would mean you do not have permission to like any of the other titles in the store.

...OMG, guys -- GOG is telling us what we can and can't like! EVERYONE NEEDS TO GET OUTRAAAAAGED OVER THIS!!!

=P
