In addition to the already mentioned titles, I've picked up The Witcher 2. Figured I might as well get it on sale before it goes back to regional pricing.

Not a bad word about GOGs fair pricing scheme - I greatly appreciate it - but it would still be more money out of my pocket.

As a Sierra fan, I picked up all the Quest games that I didn't own. I hope GOG releases Liesure Suit Larry and Quest For Glory in the future. I picked up a few other games for my self and a few gifts that inluded 2 games in my giveaway.

I couldn't pass up the opportunity to get both Blake Stone games for myself, along with the Might & Magic 6-Pack, Psychonauts, Swat 3, Die by the Sword, Serious Sam: The First Encounter, Pinball Gold Pack, Duke Nukem the Manhattan Project, and Rise of the Triad.

I also picked up the first two Gothic games, although the first wasn't featured in the sale.

All in all, I'm very pleased. Now if only I could find the time to play all of them!

The Incredible Machine Collection, Fallout 1 and 2 I bought together.
The week after I bought Populus 2. I was planning on buying a couple for my brother to play (Neighbors From Hell, Alone in the Dark Collection, Painkiller, Evil Genius) but he decided against them so I just got what I wanted.

Freespace 1-2, Advent Rising, Total Annihilation, Shattered steel, Little big adventure & Sanitarium. I've also won Realms of Arkania 1-2, B-17 flying fortress & Arx Fatalis. Only had time to finish Freespace 1 & Advent Rising, and I've just started B-17.

I bought both Baldur's Gates. The fact that my mouse is in another city is starting to piss me off.
