Ref: It's like a giant hug: From Wishlists, With Love Sale now on!.

TLDR: That was the 55 most-wishlisted games on sale. This time might have the additional gimmick that instead of the regular "same freebie for everyone", it'll have a custom freebie based on your wishlist? That'd be neat. I'll assume here that "active" is just "visit the homepage during the sale", so that it mostly works the same as other freebies, and the only quirk is the random game.

I considered doing that. The question is how the free games will be distributed.

- Are they randomly granting one game from everyone's wishlist without other constraints? If so, having only expensive games on your wishlist is good. But they then run the risk of having lots of users game the system by only wishlisting Witcher 3 GOTY, and they probably took that into account.

- Are they maybe monitoring the average value of wishlist-items for all users, looking for signs of trying to game the system, and punishing that by modifying the probability that you'll get a game in a certain price-bracket?

- Are they re-using the code from the pinata/star sales, and drawing a random game from a pre-assigned "pool", just this time without us having to pay $x.99 for it, and limited to only using the subset of that pool that matches your wishlist? (Knowing gog, that setup sounds likely.) If so, then if you can manage to be on the homepage immediately after the sale starts, and have at least one expensive game that's also in the pool (hint: look at those pinata/star sales), it'll pay off. But of course they'll mostly have cheap(er) games in the pool, so if you're not there right at the start, or have an eclectic taste that doesn't have overlap with the pool, you might just not get anything.

- Are they pre-assigning game matches from such a pool/wishlist combination for all "active" users (where "active" there is actually having posted on the forum / bought a game recently), so that the timing aspect doesn't matter? "Non-active" users in that scenario just wouldn't get anything / only get a cheap game from the remaining pool. Seems like too much coding effort without any benefit to gog itself, so I doubt it.

Lots of other permutations and possibilities I can think of, and nowhere near enough information to go on. In the end, I'm just going to leave my wishlist as is. It's my wishlist, for my benefit, and I'm not going to tweak it for the benefit of further marketing. (Though yes, of course, having it stored in gog's system is already giving marketing 90% of the value; and in that case I'm happy about that for them.)
