Lexor: It also can just the matter of pure advestisement (to let Amazon users find out "what is this GOG?") with no money involved.
JP4n: That would be a horrible deal because people pay Amazon for a subscription, while GOG burns games from its catalog just for such ridiculous advertisement. Many of those games are important.
"Important" is a really loose term, and there are tons of players who don't care about those free games at all.
And the "horrible deal" is not that different from the past GOG Connect. There are games that can be activated free on GOG, and the assumption is that some people who get the free games will later become paying customers.
Obviously that didn't work as intended with Connect, I'm sure not even GOG knows yet the exact outcome of this Prime co-operation.
It should also be noted that there are several platforms involved there, GOG, Epic, some others, you can even count Big Fish Games because there's at least one game from their store every month, even though it's an Amazon Prime download. So it seems as if all these other stores are doing this to get some market share from Steam, as there hasn't been a single Steam game ever in those Prime offerings.
JP4n: Have you considered who will pay full price in the short term for any of the last 4 months selected games? Also, who will keep buying a single game directly to GOG that costs more than $4USD when you can get over 10 GOG games and many more on other PC platforms for such low price?
Well you sure have a point there.
And this is GOG we are talking about, who once upon a time was talking about the risk of devaluing games, and had no discounts over 40%, and even those were rare.
But GOG has long ago decided to get rid of that core value. So whether they devalue games by offering something for free or with enormous discounts here, or have some GOG codes in Prime, is really a technicality.
They no longer care about the whole devaluing issue.
