Only bought 3 games from which I already owned Powerslide (I couldn't get mine to work without graphic glitches), the other two were Re-Volt and IHNMBIMS.
I also got the Fallout games of course even though I already have them physical too.

I was thinking of getting European Escalation as well as it looks damn interesting, but seeing how much of the games I buy collect dust I postponed it until later.

I've only bought Leisure Suit Larry Reloaded.

Would've bought the Roguelike Bundlelike bundle, with Spelunky and Rogue Legacy (I already have the other games from the bundle) but unfortunately I've missed it :(

Only found out after the bundle was over.

Oh, well - I have games to play anyway, gonna pick up Rogue Legacy the next time it appears on a nice sale.

From GOG I bought Tomb Raider 1-3, Shadow Warrior, Valdis Story: Abyssal City and Two Worlds 2. I also bought the new Tomb Raider from Amazon.

I'm pleased with myself, because except for TW2, I started playing all of these immediately instead of just throwing them on the pile. I've done better about not buying as many "maybe someday" games as I used to.

Only purchased:
Entomorph
The Lords of Midnight

Got:

Fallout games (from GA)
Stronghold Crusader HD
Total Annihilation
Smugglers V (currently playing, it's awesome!).

I got the Fallout Bundle the day I signed up and later bought the entire Ultima Series

Welcome to GOG!

Fallout Bundle
Wing Commander I-IV
Ultima 1-3
Re-Volt
Tomb Raider 1-5

All classics, and so far enjoying every minute.

Only games I didn't snag were Unreal 1&2, which have been due for a proper sale for a while now.

Hi elendiel7, How were you're holidays?
I only managed to get the fallout games (thanks GoG!) Otherwise I was broke, spent to much of to little for Christmas on my family.

Everything on GOG is DRM-free.

You may have to have a unique serial number to play a few games (Neverwinter Nights 1 and 2 are a few examples). Those games need the CD serials to keep track of unique player IDs, so it's integrated right into the game.

Free:
Fallout Tactics (already had the other two)

Daily deals:
Defcon
Fist Puncher
Hammerwatch
Shelter
Surgeon Simulator 2013
Symphony

Bundles/regular sale:
Advent Rising
Aqua Kitty: Milk Mine Defender
Fantasy Wars
Freedom Force vs. the 3rd Reich
Hitman: Codename 47
Might & Magic 7
Might & Magic 8
Might & Magic 9
Postal: Classic & Uncut
Wasteland

Picked up the following on my wishlist:
Darkstone
Deathtrap Dungeon
Project Eden
Rune Classic
Smugglers V
Volgarr the Viking

They were really good. I got to spend some time with my family, although not to the extent that I wanted. Other than that, I did get a lot of things that I wanted.
Any chance you have gotten around to trying Hammerwatch?
