Unregister a game?

[unmerged(70178)]

Hi!

I registered eu3 complete a while ago, it is the CD version. I saw here in Hungary in a webshop the eu3 chronicles (CD version), and i'm planning to buy it. They are the same game, but the chronicles has the last add-on too (Divine wind). Obviously i don't need the game twice, so is it possible to unregister the eu3 complete - after i registered the chronicles - in order to sell it someone? So if someone buys it, one could register it too.
Downloading the add-on isn't an option to me, because i like owning my games physically, all my games are on the shelves in disc form.

Thank you for your answer!

No, you cannot unregister your games here, sorry. But you can register Chronicles as well, they do not conflict at all.
