So I still have unredeemed codes:
1x Alan Wake's American Nightmare
1x Dungeon Keeper Gold
1x Giants: Citizen Kabuto
1x Rise of the Triad (2013)
4x The Witcher: Enhanced Edition
1x Torchlight

I either got them when GOG gave them away for free or for free with a purchase. The order list doesn't list them as expired.

Today I will drop here a code from time to time, and if I don't finish today, then tomorrow.

Dropping open codes is considered bad form around here so I would advise against it.

There are plenty of other ways to give them away, just make a human answer you aka MAHAYO. :)

please dont - please make a human answer you and consider the knock on effect for the rest of us.

thankyou for the giveaway though! :)

Edit: Error in ? hint

I have this game already but solved the puzzle for the sake of curiosity. Is NTFS really a default? I think the FAT32 is.

BTW, it says the code is already used.

Thank you for the gift...merry christmas

NTFS is the default on the Windows NT line, and the two Windows lines merged. At least since Windows XP, NTFS is the default. There is also this list on Wikipedia.
