No need to apologize, Felderburg, that's what this thread is for. We get codes on Steam, GOG, etc. on occasion that we can't use (bundle deals when we already have the game in question, mostly), none of our friends want particular codes (most FPS fans don't dig MMOs, and vice versa), and worse, some have a time limit. Posting them here, they're first come first serve.

At least somebody gets a free game out of it versus letting it expire. If you can use it, punch it in. No permission or apology needed.
Enjoy your new game!
