MarkoH01: I already mentioned this and support also told me so (which I quoted here as well) after I did not receive a giftkey when I bought the bundle as gift for myself. But yes, I guess too much confirmation can not hurt ;)
Exactly, more confirmation is never a bad thing.
Also, I wasn't sure if that applied only to games you didn't own but we're part of the bundle or to all games in the bundle, I knew you be forced to accept it if you didn't own it but wasn't sure if it would generate a key for a game you already owned.
I probably missed something important, this thread has been rather chaotic since the anniversary started, but I only knew for certain that I'd be forced to accept a game if I did not actually own a copy already.
