It's seems I pretty much get what I don't have I got

Albedo
Grimrock 2
Superpower 2
Moebius
Octodad
The Fall
Sanctuary RPG
Dead Synchronicity

And that only leaves

Ironclad Tactics
and 2 Ys games I don't think I really want.

IF the list on page 1 is accurate.
'
I went ahead and got 3 more and got
Ys 1 and 2
The Other Ys
and finally Ironclad Tactics

but I should have every game now.

Someone please stop me from doing this ever again. Got Unreal Tournament 2004, a game that neither I nor my husband (who usually will use what I won't) will ever ever touch. There's only maybe three games on there that are just absolutely-never-no-way for me, and that's one. What are the odds? (Yes, I could calculate them. I'm being rhetorical.)

It must be rough, sweating pure luck and all :D

Noooooo, bring back the £3 and stick of warm gum.

*spends £3 on a winning set of scratchcards and tips the puzzled shopkeeper with a stick of warm gum

Excuse me, I didn't quite catch you there... What game did you get as a Mystery Game?

I'm not quite sure but I think he's trying to say he got Jack Keane.

Do I try it one more time or not, do I try it once more or not, ...ah damn, I want an Insomnia Sale.

All hail the Keane.

It has nothing to do with luck.

GOG gives absolute priority to games you do not own (on GOG), as long as the allotted quantities last. WhoKnowscs simply got all the games s/he does not own, as expected.

Yes, you can, it's stated in the sale FAQ.

TOWER OF GUNS

Defender's Quest

I just got Halfway

Does the wishlist have any effect whatsoever on Mystery game drops? So if I really wanted a game that is on the mystery game list, could I deselect any other wishlisted titles that are also on the list and have a better percentage chance of getting it?

Well I tried one more mystery game and got Omerta.

So my mystery games are:

Aquariana
Gurumin: A Monstrous Adventure
Space Colony HD
Superpower 2
Shantae: Risky's Revenge - Director's Cut
Omerta

Guess I can count myself lucky that I got no doubles for games I already own on Humble Bundle.

Your wishlist has no influence on the game you get. The algorithm looks only at the games you already have in your library and chooses preferably one you do not own already.
