WooHoo! Way to go gog!

"Bought from GOG", or "Owned, and sold on GOG".
If the latter:
1nsane
Descent 3
Die by the Sword
Evolva
Fallout 1/2/Tactics
Freespace 1/2
Giants
Hostile Waters
Kingpin
M.A.X.
MDK 1/2
Messiah
Sacrifice
Stonekeep
If the former: nothing at all. :P Definitely going to get JA2: UB, but it's troublesome to decide what the other game would be to make use of the buy-one-get-one-free deal.

I has bought
Fallout 2
Giant Citizen: Kabuto
Freespace 2
on gog. :D

I've bought (well, bought one, got the other free) two: Fallout and Die By the Sword.
I do have disc versions of several games here, like:
- Evolva
- 1nsane
- Sacrifice
- Hostile Waters
- Shogo
- Perimeter
- Colin McRae 2005
- Operation Flashpoint
- IGI 2

Will soon buy mdks, JA2 and giants. when. don't know.

I own:
MDK 2
Perimeter.
My brother owns:
Die by the Sword
Shogo
Redneck Rampage Collection
Currently I think about Sacrifice.

I bought Freespace 1 and 2. I will bought Fallout and MDK Series soon.

GOG.com games that I own:
-MDK
-MDK 2
-Die By The Sword + Limb from Limb
-Hostile Waters: Antaeus Rising
-Giants: Citizen Kabuto
-Redneck Rampage Collection
Games that I have hard copies of that also happen to be on GOG.com:
-Die By The Sword (no Limb from Limb, though)
-Redneck Rampage (but no Route 66 or Rides Again)
-Descent
-Descent II + Vertigo Series (the latter of which seems to be missing from the GOG.com installer)
-Descent 3 + Mercenary
-Freespace + Silent Threat
-Fallout
-Fallout 2
-Operation Flashpoint: Elite (Okay, this technically isn't quite the same since it's the Xbox version. I'd prefer that type of game on my PC, but I'd rather save up for Armed Assault since my new PC can handle it.)
Games that I have hard copies of that aren't on GOG.com:
-Way too many to list

I've bought:
Fallout
Fallout 2
Descent + Descent 2
FreeSpace 2

I own:
Original War
Giants: Citizen Kabuto (Free Game)
Redneck Rampage Collection

Original War and Fallout Tactics, and I'll probably pick up TOCA once it comes out, since I freaking love that series.

fallout one and two, and redneck rampage collection, so far.

I own the Fallout collection (1, 2, Tactics) and am going for MDK 1 and 2 and Giants: Citizen Kabuto. I may also buy Evolva and Sacrifice, although I already have a collectors edition of Sacrifice (I also have a CD version of Fallout 2 but that didn't stop me).

Got the three Fallouts and Giants: Citizen Kabuto so far. Planning to buy CMR05.

So far:
Fallout
Fallout 2
Fallout Tactics
Freespace
