Makotolia: May I request Drakkhen and The Bureau: XCOM Declassified (†)?
Also, I have some little problem understanding the Humble link dear finkelroy offered: as per the DRM-free copies, does it mean that I'll have to download and keep copies to my self, or...?
The link permanently adds the DRM-free copies to your Humble Bundle library. You can download the games directly from your browser while you're logged into your account on their site. You don't have to back them up, like you would with the Humble Trove. It's just like GOG with the offline installers. Separately from this, you also get Steam keys added to your Humble account. You can either use them to activate all 6 games on Steam, which would give you two copies of each game, one in your Humble account and one on Steam, give them to a friend or family member, or you can stick with the DRM-free copies and donate the Steam keys back to the giveaway. If you keep the Steam keys, this counts as one game towards the monthly limit, but if you donate the Steam keys back to the giveaway, this does not count towards the monthly limit of games. And you get all six games. I'm surprised nobody's requested it yet. Someone requested just the Deponia complete edition, which is the first three of the four Deponia games, though, and I'm pretty sure it's a popular series of games.
EDIT: To be clear, the Humble gift link is for the following games: Deponia, Chaos on Deponia, Goodbye Deponia, Memoria, Anna's Quest and Caravan. If you don't donate the Steam keys back to the giveaway, this counts as one game towards the monthly limit. If you do donate them back, it doesn't count at all, like it's daggered (†).
