I know probably most people already own the game as it was featured free some time ago. I just forgot I got it for the second time, and it has been sitting as a gift on my account until now. To earn the game, you will just have to solve this little puzzle. Each point is a letter of the gift´s code:

1) First letter of a 2D viking platforming game featured on GOG.
2) Third letter of a GOG´s game featuring "The Jupiter Incident".
3) A number: http://www.youtube.com/watch?v=1ZeciX-3wfs
4) First letter of the last game on Xbox360 from Sakaguchi.

1) First letter of an IP that was featured on GOG until this year, which was free for some time. It has only returned to Steam yet.
2) First letter of the absolute king in GOG on the Insomnia sale!
3) Last letter of the game: "It is the nineties and there is time for...".
4) First letter of the kind of dog featured in this video: http://www.youtube.com/watch?v=GrIp3k5pJQM

1) Second letter of the game featured in this gift.
2) Only letter of a game which has been released to GOG on this week, which is a port of a mobile device instead the old PC version.
3) Flip vertically the most used letter on this video: http://www.youtube.com/watch?v=5qwKZXN0WZI

4) This egg was featured in several 8-bits titles. Spellbound was his # no-spinoff game.

If you get the correct code, the game is yours :P

Still not redeemed?

If you are interested in the game and you have trouble getting the correct code feel free to ask.

bump Dungeon Keeper gold is one of the best game ever

Probably all the people who've been on GOG long enough to answer this one have been around for long enough to get the free copy :P

That's quite a complex giveaway!

Already have it but +1 for the generosity

Cool idea for a giveaway - I've already got it though.

I did just get it recently, so had you posted this last week, I would have been madly trying to figure out the code.

Really complex! Nice idea. You should also post the answer after the GA. Some really interesting questions I'm sure we'd all like to know.
youtube isn't working for me though, and my folks will bash me for being too hooked on the PC if I take the time to search.

I truly agree. I´ve replayed that game too many times, and I´ll keep doing so :D Yeah, I´m starting to think that´s the case... If nobody redeems it I´ll try a more simple version. Thanks! ;D Enjoy the game! It´s a masterpiece :) If you are interested I could post some more tips :P I expected some more competition when I posted it.

No need bro. I want your game to go to someone who'll 100% enjoy it. I'm sort of an on/off guy when it comes to RPGs and I'm not very fond of the genre.

Solved it! Thanks for the game!
