I just wanted to say I feel sorry for all the people that are annoyed and feel like they were wronged and mislead by GOG.
Just to make this clear, since someone accused me of being "paid by GOG" on The Witcher 2 subforum just because I was defending them, GOG doesn't offer me anything, aside stellar customer service and a selection of great oldies and indies at affordable and fair prices, all DRM-free. I know how this sounds like PR speech, and I understand how I can come across as some sort of GOG "undercover spokesperson". I am not. I feel genuinely that way.
I feel really bad for all of you who tried getting The Witcher 2 for free (and The Gamers, as well, even though no one seems a bit interested in that awesome movie) and are experiencing problems getting your e-mails. I also know I sound obnoxious as hell by saying people should "just be patient and optimistic", but that's all I can say, right now. Like I said, I'm not on GOG's payroll, and I have no actual idea of what's going on, all I can do is speculate.
Please, make sure the e-mail address you entered when you created your GOG account is an active one, because that's the address you'll get your codes in. Be sure to check your spam inbox, as well. Don't spam GOG support with trouble tickets right now, because I'm sure they're answering them all as fast as they can, and they're trying to sort these things out. Of all the interested parties in this, GOG has the most to loose, so trust them a bit more, they're the ones who can't afford losing potential customers and having this kind of bad publicity.
I haven't been on this community for long, but I try to be an active member as much as I can, and this isn't my first GOG promo giveaway, and all I can say to you is that this whole process isn't as automated as something you'd expect from Steam, for instance. Steam is a behemoth of a monopoly, and they can afford the infrastucture to support promos like this one way better. GOG is a much smaller company, and these things tend to be slower and less "fluid". If it's of any interest to you, you also get a much more personalized support from GOG, due to it being a much smaller -- and, thus, much more human -- company. They take longer to reply to your trouble tickets because they have actual people replying to your issues, one by one.
This isn't to say you shouldn't feel bad -- you absolutely should, it's your prerogative --, I'm just trying to say I wouldn't be so hard on GOG. After all, it's not like you paid an absurd ammount of money for a product that wasn't delivered.
