Including the games you bought from gog.com, including games you bought or you got from your relatives,friends...
I did not get any game (I prefer money with which I can buy the games afterwards : )).
But during holidays I bought (from retail):
Bioshock
Assassin's Creed
Race Driver GRID
Mass Effect
Far Cry 2 Collector's Edition
Hitman Anthology
Hitman Blood Money
Jade Empire Special Edition
Gothic Saga 1+2
Gothic 3
Mafia
Chameleon
Deux Ex Anthology
Plus from gog.com I bought Kingpin.
All in all about 200 dollars only on games....damn : ).But I almost prepaid the whole 2009, because probably the only other games I am going to buy this year are Mirror's Edge, Fallout 3, GTA4 and Mafia 2 (and Age of Decadence : )).
I did not buy anything from Steam or Impulse, because I prefer physical versions, and if I am going to get something digital, it has GOT to be from gog.com : ).

Well, let's see...
Bioshock
Mass Effect
STALKER
SiN Episodes
Spellforce 2 + expansion pack
Darwinia
Uplink
Left 4 Dead
Earth 2160
Broken Sword II from GoG
... And I guess that's it.
Deus Ex Anthology? It's actually sold somewhere in Czech Republic? I HAVE to check that out...

Yes, through Cenega. I know, because it's also available in Poland.

Yep, I bought it here:
http://eshop.megahry.eu/Kolekce-Klasiky-Deus-Ex-Snowblind_g715.html
Two great games (yes, Invisible War is a great game) plus one good (though I have not played Snowblind) so cheap..

And it's so cheap? Thank you both, I have to buy that...

How is it?

I got it from Steam for only $2.5. Combat is solid, graphics are very good and system friendly, story is not good at all, controls are fine but voice acting is terrible. If you like Doom 3 or Chaser you will like this too. I know it can't race with huge budget titles but for $2.5 game is very good. Also enjoyable and has 20 hours of gameplay.
