Most rage for not being able to play Command and Conquer Generals: Zero Hour online, because it says my serial number is wrong. However, it's right, because it's on the box. And they don't support the game anymore, so I can't get help. Of course, NOW it is wrong, because I got the game a few years ago and lost the box along the way, and I just got a new computer and getting a replaceent serial number costs 10 freaking US dollars. But before it was correct, and it still said I had the wrong serial number. And Command and Conquer is my favourite game ever, so it sucks. No one can match my rage over this, thus I hold the world record. And I don't care that this isn't a real category, because it should be.
