It's a very nice list but far from complete, amongst others: No Tex Murphy 1+2 No original Fallout giveaway and no later Fallout 1+2+3

Check PM :)

I found a gog key for Earth 2160 on a Bundle and i think (almost sure) it's unused, anyone wants to give it a try?

You can try to redeem it without using it. GOG tells you what is the key for, if it expires and will ask you to confirm the operation.

Oh, thanks for the info, so, the good news is that it wasn't used, the bad news is that i got this message "Code expired on: June 30, 2014".

Nothing to see here, move along...

Wouaow. Thank you for your generosity ! This is really awesome you makes me so happy :D
*go downloading*
Finally, I'll be able to play Locomotion again !! (and to discover Silver ^^)

A last time : thank you !

If anybody has left over code for Dungeon Keeper 2 or Divine Divinity and would be so kind to gift it, I would be very grateful.

Thank you :)

Thank you very much you are a true hero! :)

Here's my wishlist from this weekend's promo before it ends if anyone would be willing to get it:
Red Faction II

This doesn't sound right, codes are supposed to last till year end, what exactly happened two weeks ago?

Do you have a reference for that?
I thought promotion codes can have different expiration periods completely non-related to the end of the year.

Not sure but i found about this gog key when searching for old bundles that i bought, this was found on Be Mine 6 that i bought on November 30 2012.

Lookin' for silver if anyone wants to oblige, it'd be awesome, it's on sale for $1.79 :)

Oh, if the code lasted over a year then yes, it could end any month (one year AT LEAST from issue*, rest is extra niceness).
I thought it was under a year * the codes from the microid bundles will work until end of this year as they were issued earlier then those bundles.
