O.K., I´m a bit too late: (1st anniversary was on 11th of June...)
But hey, everybody sometimes miss a explicite date:

So I´m now celebrating the first anniversary of this forum-account!
You can win the Humble Bundle Steam-Key for Psychonauts, Costume Quest and Stacking! (all in one Key)

The rules:
1. More then 10 Rep or registered before 2013.
2. You can do everything you want with the key!!!
3. I´d like you to write a little paragraph on a non-well know, but fantastic game on GOG!
4. Winner will be chosen by ME at the end of the month:
No personal relationships, only quality of the entries is counting for me!

Not in, but thanks and +1 for your generosity, Radon!

Congrats on your anniversary, mate. Hopefully this will be the first of many. :)

Happy Anniversary, Radon! Thanks for all of your puzzles (how many hours have I spent scrolling the wish list ;-p) and for the giveaway! Not in ;-)

I have them already. But thank you!

I'll enter for the first person to actually enter the giveaway. :-)

Well, this could only be counted if you´d actually post a little paragraph...
