the unthinkable has happened! Apparently Mount & Blade sold so well on Steam that they ran out of CD Keys!!! Now Valve will have to get more CD Keys (should take 1-2 days) but by then the 75% Off M&B deal will have expired.

Whose bright idea was it to have CD keys for digital distributed games?

 

 What else would they use? The key is everything, it's proof that you actually paid for the game.
