It was World of Warcraft. World of Warcraft killed DAOC. It was sad.

Ironically, WoW has no player housing whatsoever(or had, i haven't touched it in ages). So a good housing system wasn't enough to resist the siren call of WoW...

Of course WoW's siren call was more like that scene from The Simpsons where the sirens turn out to be Patty and Thelmma. But people still played it.
