Gothic 2. It's the only game I've ever heard anything about on the list, and I do hope that it shall be good.

I went for Divine Divinity, it's really good and I'm having a lot of fun with it. I can't believe I missed getting it when it was first released. I have put it down for now because I don't want to delay playing TW2 tomorrow, but I'll definitely come back to it afterwards.

Realms of Arkania 1 and 2 - Double Pack.
The ROA games are the only ones I'm missing out of those available.

I already own Gothic 2 and those two Divinities.
Actually, I don't have Night of the Raven expansion, though.

Gothic 2 - more fun than a bag of weasels!

Beyond Divinity.

I already had Divine Divinity and Gothic 2.

Divine divinity, damn 1.6GB that's huge for a free game :D

I went for Realms of Arkania 1+2: In addition to the reasons below, the GOG description and reviews of RoA 1+2 made it sound really interesting.

I didn't get ____ because ____:

-Beyond Divinity: I read up a little about it. It didn't get a very good response.
-Divine Divinity: I've played a little of Divinity II, so I was aiming to get this at first. Then I found out it was an diablo-like ARPG, and I'm a bit tired of those for now (I don't consider The Witcher the same type of ARPG). Maybe I was wrong about DD, but oh well.
-Gothic 2: I already own this game.
Realms of Arkania 3: I haven't played the first two :P

Divine Divinity. Fooled around in the first part a little, but it's just hard for me to do old graphics these days.

How do I find the $16 credit? I don't see it anywhere? Do I just add something to my cart?

Me too
