Bundles:
D&D Bundle - I have a hard copy but hell, those games are so awesome I want them here as well.
Witcher 2 - I still have the first game to play but at that price I couldn't say no to it.
Daedalic - whole bundle; already had A New Beginning hard copy, but I wanted the rest so now I have both hard copy and GOG.
Santa Snapped - aw, guility pleasure : )
Sierra Quests - as an adventure fan, I have to play them finally.
Scandinavian - had Alan Wake, boutht Riddick.

From my wishlist:
Broken Sword 2, 3 and 4.
Personal Nightmare
Bioforge
Bloodrayne
Litil Divil

Surprises:
Assorted Indie Adventures - to my surprise I opened the page of that bundle and already had every game in it : )
Belated Halloween - just like Assorted Indie Adventure, had them all before the promo...

Easy. I just bought whatever you folks recommended to me, and I'm loving all of it. I don't mean to sound corney or like I'm brown nosing but hey, this forum is a gold mine.

Summed up: Too many.

City Builder bundle for Pharaoh
Santa in Space for Moonbase Commander
WWII for Medal of Honor primarily but I will play some others as well.
Likely to still buy the Bullfrog one in the last hour for Theme Hospital.

I had a few games in each bundle purchased so it wasnt full price on all, but i think around 50 bucks. Getting Moonbase and Pharaoh were by far the greatest grabs for me this sale.

On the flip side of those feeling bitter about games included in a bundle they do not like, I would purchase for one game. While I spent more than I would have buying it at 50% on its own it appealed to me getting a large amount of games on the cheap. And since I dont kid myself that I will ever play a quarter of these for anything more than a few hours, its basically a collection thing anyway. I am GOGs ideal customer... I give them money and dont even take up DL bandwidth.

I bought Trine and could not resist The Witcher 2.
I think this will be enough for quite some time, as I have little free time to play games nowadays.

Wow, my total is $213.68 in the christmas sale.

Only four games. Uplink and Lord of the Realms, and only yesterday Master of Orion 1 + 2 and Silent Storm 2 Gold Edition.

I was also thinking about grabbing Hitman 2 but missed to pick it up when it was still reduced. No problem though as I have still more than enough games to play and am sure that it will be part of some special deal sooner or later on GOG.com anyway.

Alan Wake: 7.49 Dollars to Remedy
Alan Wake's American Nightmare: 3.74 Dollars to Remedy
Duke Nukem 3D: 0.0 Dollars to 3DRealms

Total: 11.23 Dollars spent

Was tempted to pick up quite a few $2.99-$4.99 games from my wishlist but figured that I'd rather spend more at a later point when money isn't so tight than spend less now when it is...

I bought the following titles:

Bullfrog bundle (I only had Theme Hospital)
Anachronox (from the Cyberpunk & Steampunk bundle)
Heroes of Might and Magic 5 bundle (from Might and Magic Madness bundle)
Dangerous Dave Pack
Duke Nukem 1+2
Gothic
King of Dragon Pass
Shadow Warrior Complete

I got Inquisitor... and that's it.

In my defense I took full advantage of previous sales and had nothing else I really wanted to buy, really.

Might and Magic Madness bundle and Zeus + Poseidon, Lords of Magic: Special Edition and Lords of the Realm 3 to complete City Builder's Special bundle.

The lack of ability to pick up individual titles at 75% off meant I didn't buy nearly as many as I really wanted, but a strong finish thanks to a trade.

The Witcher 2
Torchlight
Legend of Grimrock
Trine
Giana Sisters
Carmageddon
Botanicula
Wallace and Gromit
Monkey Island
The Incredible Machine

Wanted some other titles, like The Longest Journey, but am hoping it comes on offer with more than 50% off. The Incredible Machine is so left-field I guess it's less likely to be on offer any time soon (probably next week! :D), and I had a lot of fun with it way, way back, so picked it up at the death.

Some great offers in the beginning of the sales period, but the 75/50 stage left me cold.

Nothing. My backlog won this Xmas.

Maybe a dozen or two GOGs earlier in the promo (mostly during the end of the world sales, I listed them in some other discussion), and now I was about to clear my GOG wishlist with over 30 games (about 140 USD in total, all of them 50% off)... but the GOG billing system bugged out (money was reserved, but no games came to the account) and GOG support hasn't replied quite yet, so let's see if I will obtain those games or get the money back.

After last year I saved up for this years sale on GOG, I'm not sure about the specific breakdown but I spent over $200 here on GOG during this sale (completed most, if not all bundles) and then started doing gifts and giveaways.

At a guess the publisher that got the largest slice of the pie was CD Projekt since I gifted more than one copy of The Witcher 2, and give out The Witcher as well.

I hope it lasts me because I'm not what can be considered wealthy and I think I've spent most of my games budget for 2013 at least until Aug (if not longer)
