In any case, the players could feel the energy and enthusiasm the game company had when they were designing Blackrock Abyss. This Instance Dungeon almost didn't feel like a game.
There were so many quests in it, but there were few quests that were required.
The Blackrock Abyss existed to show the Iron Dwarves' way of life. The game designers thought this meant that there should be a huge Iron Dwarf city in Azeroth. This city had prisons, taverns, mines, arenas, and royal palaces. There were members of different social classes performing their duties and maintaining order.
As you walked past the steel gates and down the road, this feeling became particularly strong.
