All Paradox games come with a cd-key which is used in the paradox forums to register the game. As I recall that is so legitimate customers get a higher priority for support.
Not sure I understand what you mean here.

Sorry, I'm mistaked the bonus with the pay more than average.

Fair enough, I just wondered why it was listed as DLC. Made it seem as though you had to pay to register on the forums, which would be a quite innovative and completely bastard-like way of fleecing customers.

I grabbed it for Orcs Must Die 2 because I loved the first game, but I have to say I am very disappointed they have replaced "DRM Free" with "Redeems on Steam", like that is a selling point.

Unfortunately, to many PC gamers that is a selling point. Sad.

I am doing a giveaway for this if anyone is interested.

Another Steam Sale ... it really disgusts me that even in the Humble Store there isn't any real way to sort for only "DRM Free" games, or even to filter what games REQUIRE steam from games that OFFER steam versions.

How the mighty have fallen, seems like the true final act of THQ was to drag Humble Bundle down into being just another Steam Key supplier.

Odd question. Which of these games have trading cards? (might as well squeeze a bit of $$ out of steam and get some games i actually want)

All of them.

thank ye Triock :P

Strange selection although i do fancy sanctum 2

I'm really starting to hate this steam key linking system now and because of it am not buying the latest bundle. Not being able to choose what games we wants to redeem means I would be stuck with games on my wishlist that I really don't want and have no intention of playing ever. (Sanctum 2 in this case, I hated the first one.)

Only games I do not (yet) have is Natural Selection and Sanctum 2. The former being a MP only game, I do not really care about... just have to see in a weeks time if there are going to be some bonuses making it worth picking up.

Originally I thought maybe there'll be more people to play NS2 with. Nope, apparently no-one in Asia Pacific plays NS2 (CORRECTION: just the right amount of people in the Asia-Pacific play NS2 so that I'm the odd one out)

I'd LOVE to jump on & play Sanctum 2, but it flat-out refuses to let me join an online game.
