bmanbdaman: Hmm, nothing I really wanted, but some I think I will like. Was worth giving it a smack.

Eschalon: Book III
Banished
Consortium: Master Edition
Unrest
zeroxxx: Eww Banished. Would love to get that in pinata, but knowing my shitty luck I'd refrain on gambling.
Well, I did try the piñata the second time around after the first time failure (getting three games I already owned). But then, the first time republique was the only one I didn't have, and it was very limited, apparently.
This time a tried two times and got the only ones I didn't "have"; Hot Tin Roof and Sword Of The Stars: The Pit Gold Edition (yeap, I had every other combination of sword of the stars, including the gold update, but this still counts as new).
So maybe the algorithm works as long as there are games you don't have in gog that aren't limited in the sale.
(I got the piñata without the gift option)
l8r!
PS: And yes, a tried it close to 12 when the new piñata showed up, without knowing the games available. Got Hot Tin Roof first. Wouldn't have tried the second one knowing the game list.
