To think all I was going to do was buy Fallout 2 and Operation Flashpoint...then I decided to take a cheap risk and buy Ghost Master since then I have become addicted to GOG. :D

Kudos to you. There are some I just can't bring myself to buy, but I'm planning on getting many more than I'll have time to play for the same reason, but I have to limit myself to one or two a paycheck. GOG Rocks!

Fallout 1 and Fallout 2. Stopped at Arx Fatalis release, due to 1.19 patch debacle.

56. A few more games and it would be easier to list what I haven't bought instead of what I have. (Give it time)

Only one so far (the guild gold), however I'm VERY happy with my purchase and I'm almost certainly going to get more in the future!

Broken Sword 3
Flatout
UT 2k4
UT GOTY
Sacred Gold
Descent 1+2
TOCA 3
Fallout Tactics
Giants
Fallout 2
Fallout
That's 11 games, and the only one I finished so far is Fallout. :D

Got 20 including the freebies at the mo :)

Well, 28 so far including 2 freebies and I'm sure I'll be adding more. At these prices, it's hard to resist and very convenient.
