My favorite now-lost moment? The Battle for the Undercity, which used to be the epic conclusion to the Wrathgate quest chain in Wrath of the Lich King. Today, if you finish the quest chain, you are sent to talk to Alexstraza, who no longer has a follow-up quest to give you. The event now cuts off abruptly, without any kind of conclusion -- and if you quest your way through WoW today, it's not the only story element that's been lost to the changing nature of the game. So tell me, readers -- what are your favorite memories of gaming moments lost to time?
