Only enter to win games you do not already own, and do not enter to win DLC if you are missing the required base game.

Ah, I guess that does make sense. I just read it as the rules stating not to enter a DLC giveaway if you do not own the base game.

As the FAQ says

    What are the rules for entering to win Steam packs if I currently own a number of the games contained within?

    We ask users not to enter giveaways for packages if they already own the majority of the games. This allows for winners that will receive the most value out of their gift. In the end, the giveaway creator has the final say, and if they believe the winner owns too many of the packaged games, we'll allow them to request a new winner.

Either way, I will not enter just to be safe and I appreciate the generous giveaway :)

Well, it actually isn't against the rules to enter for the DLCs. But if YOU decide to send the key only to someone, who doesn't own anythimh from that bundle, then it's alright - it's fully up to you. But it's always better to put some short description that you don't want people to enter this giveaway for DLCs. I won't enter this one as well, as I already own the base game.

thanks, all worked well
