Is this the same for all?
I mean, the same game for all?

For the last two days I get games I already own so....yeah.

Random draw for everyone.

There's a list of games for each category. Everyday it randomly selects one for you. You can look at what other people got here and try to find a trade if your not happy with what you have.

Well, then hopefully GOG will do something to make it not suggest a game the customer already owns, or at the very least make it so that if he already owns it can re draw from the other two.

I am just surprised that with all the games in my wishlist I keep getting games I either own or above my price range.

Price isn't really a factor, I'd just like to get some games from my wishlist. So far I've gotten three games I already own and today I got Amnesia: A Machine for Pigs for 51% off. Preferred the insomnia sale to this!

So far I've gotten games I would have bought if I wasn't such a cheapskate/already had them, so I feel like whatever algorithm GOG is using really understands me. Thanks, GOG gift box algorithm!

ps. cheapskate is code for poor (aw :c )

Not such a problem for some, but I got one offer for the Jetpack Dragon game on the first day at the same price as it was in the daily sale that day. It would not be so bad if I had been looking at the game as a near future purchase, but for not even an extra 1-2% off the price it rather missed the mark when others are getting 75% off of the latest Shadow Worrier.
Added to which is I only spend more then $10 on games I MUST own (NWN2 / H:BM). On everything else I can wait until it is at a price I feel is appropriate for the game.
Just look at Fallout, I already own them twice and felt that $10 individually was a bit much for a third time, so Interplay met me on my terms and gave them to me (and everyone else) for free.
