Nightmare Mode looks at DLC from a historical perspective, and muses over we've lost as a gaming community as a result of DLC.
"On April 3, 2006, Bethesda released the first piece of new content for The Elder Scrolls IV: Oblivion. The “Horse Armor Pack” allowed the player to acquire barding for their horses from a stable manager outside the Imperial City. This wasn’t unexpected, as Bethesda had released numerous small additions for their previous game, Morrowind, ranging from new quests to added ambient sound effects.
There was one difference. While all of the Morrowind enhancements were free, the Horse Armor cost money: $2.50 on the Xbox 360 and $2 on the PC.
The internet exploded with rage, as it is wont to do. The objections basically boiled down to two points. First, Bethesda was charging for something that had previously been free; nobody likes a price hike, and they particularly don’t like one when it’s infinity percent. Second, and somewhat more pragmatically, it was seen as a poor value. This wasn’t a new line of quests, or a new landscape to explore. It was an aesthetic change accompanied by a small stat tweak."
