The Elder Scrolls has a rollercoaster history with expansions and DLC. Bethesda's fantasy RPG series has produced some of gaming's most beloved supplementary adventures (such as Bloodmoon and Shivering Isles) and some of its most notorious DLC fiascos (horse armour). But the series' affiliation with addons stretches farther back in time than any of these releases—all the way back The Elder Scrolls 2: Daggerfall, in fact.
When Daggerfall launched in September 1996, it had an expansion out of the gate. But this addon was exclusive to copies sold by defunct US retailer CompUSA. Variously known as the CompUSA Expansion or CompUSA Special Edition, it featured 16 additional quests spread across the guilds and temples featured in the game. These quests were subsequently given wider release by Bethesda in a free patch, but they've never been added to the official version of the game.
