Mark of the Ninja Special Edition. I would feel guilt if i bought nothing from GOG...

Just Enter the Gungeon, everything else that's interesting I already had in my library.

Alas, nothing this time. Actually, this is the first time I buy nothing in a big GOG sale, but right now you could turn me upside down and not a single coin would drop, unfortunately, so there is not much to do.
I was mainly interested in Divinity: Original Sin (I had it wishlisted since it was released), Grim Dawn and VtM: Bloodlines, but it will be for another time.

Mostly DLC, with a few great games strewn inbetween:

GUN™
Democracy 3: Social Engineering
Democracy 3: Extremism
Reigns
Reigns Collector's Edition Upgrade
Men of War: Assault Squad GOTY Edition Upgrade
Men of War: Vietnam Special Edition Upgrade
Don't Starve: Shipwrecked
Democracy 3: Africa
Brothers: A Tale of Two Sons

One more piece of dlc for Democracy 3 today. Added

Day 1-5:
Nothing

Day 6:
Anno 1404: Gold Edition

Same here; i decided not to buy anything except Anno 1404 (i own the retail version minus the Venice expansion) which i bought with some GOG wallet leftovers from previous purchases. I already have several games to play in my free time so making my backlog bigger isn't something i really want right now. Also, lately i've been too busy playing music which leads to reduced available gaming time, so i think i'll wait for the next sale to do some wishlist clearing and, hopefully by then, some big backlog clearing too. ;)

As for the games you're interested, i can't recommend Divinity: Original Sin enough -- such an awesome game! Bloodlines is also a great game and much cheaper than D:OS & GD, so i guess you'll be able to play it sooner than the other two.

This was actually one of the major participation in a sale I had in some time.
It started with Interplay that allowed me to finally cave in to complete some titles I haven't been willing to get at less then 90% off,
Yet wasn't willing to buy in bulk like the older promos - also thought this might be the last time before these start to slip away from Gog as the rights move-over to other holders, so I couldn't risk hugging the borders.
Lucas Arts were never lower before (Individually) and considering Disney never went below 75% on any of its titles yet, seemed a sure bet.
I finally closed with Pax Imperia that was on my wishlist for like forever (even before it came to Gog), and had a decent 80% for that price point (so not much of a difference even if it gets 90% off down the line that would save me a swooping 0.6$).

The fact this sale was more individual title oriented even within a bundle also drove me to try wallet, as it's much easier with smaller transaction (less significant when buying a couple of bundles in comparison to numerous gifts), and the experience was quite adequate :)
