I really like GOG and would like to see the service succeed, so I'm curious. My first few questions are mostly for any members of the gog.com team and the others are for the general users.
With the prices so low during the holiday sale, I can't imagine there were huge profit margins, even though I'm sure a lot more units moved. Personally, I spent a $217, which bought me 44 games. That much money would only buy me 4 retail priced modern games. So that may be a nice temporary boost in cash from me and others like me, but the downside is that now I have so many gog games that I pretty much don't have any left in the gog catalogue that I really want. With maybe a few exceptions, I won't likely buy any new games from gog until the catalogue grows. Essentially, I've bought my way out of being a customer here, despite how much I love the business. When a few hundred is all your loyal customers can spend before you have nothing left to offer them, it seems like that can't be that good for business (except that I so love the service that I've become a proselytizer for Gog almighty). Which I imagine is the one way that a sale that big could really be successful-- by pulling in new customers.
So, was there a substantially larger influx of new gog members on the site as a result of the holiday sale and free Tex Murphy games?
Will the temporary money from the sale allow you to invest in substantially more new releases for the site to entice your existing user base to buy more games?
And questions for my fellow gog members:
Did the sale spoil you and get you used to spending even less money for games? Are you more likely to hold out for a sale than you were before, or will you buy the same amount of full price games here as before?
How many others bought so many games that you don't see yourself buying any new ones from gog for some time?
Did the freebies and the sale increase your feelings of loyalty to gog? I personally felt all warm and fuzzy when I saw I got Tex Murphy 1&2 for free and I was ecstatic about the sale. I have nothing but good feelings for gog right now. I don't know if others are affected similarly. If you do feel more loyal to gog, has it increased the amount of time you spend on the site or the amount of time you spend talking about gog with other people that aren't gog members yet?

I got on forums more after getting cheap games yeah. I also noticed that there isn't really any games I want, I got all the ones that are good to me. I think it was a long-term success, they have a user-base now and we can predict a huge turnout for the next sale next year.

Based on the number of "new faces" that have shown up here over the past few weeks, I'd say the sale was an enormous success. Unfortunately, I didn't take advantage of the holiday specials (except the freebies) since there aren't any games that I really "must have" right now and my primary gaming PC is not available to me at the moment (temporarily repurposed as a HTPC). I was already a confirmed convert to the Cult of GOG (All hail the mighty GOG, may its blessings of Good Old Games be upon you all), so the sale didn't do much more than remind me of how great this place already is.

Not a staff, but I'd like to answer the first two post:
1. I don't see many new faces in the forum after the holiday sales, though I know it's hardly representative.
2. Even if GOG only stick to their current release schedule (at least 1 new game per week), we'll get 50+ new releases by the end of the year. That's more than enough enticement for me to buy more games. If anything, GOG should spend more money on advertising. It surprised me that there are still a lot of 'hardcore' gamers (who frequently visit gaming message boards and blogs) who haven't heard about GOG or have a wrong perception of it (think it's a client-based service, for example).
And for the rest of your question...
3. I never ever buy games full-price, either in retail or digitally. It's steam sales that really spoiled me, though.
4. I have an enormous backlog, and I constantly tell myself to stop buying new games. But I have a weak self-control, so when I see a big sale coming up... :(
5. Honestly, I don't really care about bonus stuffs except soundtracks. But it does increase my loyalty to GOG; Free stuffs are always good, even if you don't really need it :P

This. My backlog is huge too, and it only seems to get bigger with time. I'll still keep buying the games here though, I can't help it ;-)

answer to first question- I wouldn't say I am spoiled but yes I am going to wait for sales. It's not that I refuse to buy a game because it is full price/too expensive. It's because I have enough of a backlog right now that I shouldn't be buying any games at all, period I have enough games to last me a long time (100 games at backloggery.com). If I see a can'tt miss deal though, I figure I might as well buy it whether I have a huge backlog or not. If I was really hurting for games, I would pay full price without a problem
answer two- like I said above, I have a huge backlog already so it might be awhile before I buy a lot of games here. The amount of time before I buy another game is dependant on much stuff I get out of the way in my backlog. I really wanna try sanitarium, so I can see myself purchasing that in a month or 2.
answer three-not really. I don't feel any sense of loyalty to any store . Yeah the deals were nice and the free tex murphy games were a nice touch, but they didn't make me feel all warm and fuzzy. It's a relatively small business trying to entice people with nice deals and to get the word spread around just like all other businesses do. Though I would definitely recommend gog to friends if I actually had any that played pc games. And I do spend a significant amount of time here, but that's more because of the posters than gog itself.

Have you tried a laxative?

I knew this was going to happen.

Perhaps he just needs to add more fiber to his diet?

*sigh* Is it time for the fart jokes already? ;-)

I'm pretty sure it's all apart of the master plan. And it's a good one. :P

Honestly, with all this GOG cult going on, we need a proper Place of Worship ;)

I don't wait for sales as the 10 bucks is not really that much to spend.
and i do have quite big backlog of games as i don't play that much...
and i tend to buy any game which interest me even tough i might not play it for a while. like kingpin which i bough almost a year ago.

Hey I'm WAY too classy to stoop to fart jokes! I was making a POO joke, completely different

As long as it looks like the Temple Of Nod, I'll be happy, that place was awesome

I admit I had no idea what Temple of Nod is.
After short session with C&C Wiki I'm now properly educated and indeed, it looks awesome ;)
But colours would have to be changed.
