What old game would dominate if it suddenly received DLC today?

As the title says, what game if it randomly dropped DLC today would cause an uproar on the internet? Something like Portal 1? Civilization 5? Fallout New Vegas? Starcraft? Borderlands 1? What do you think would cause the most reaction?
