According to a senior developer of World of Warcraft, the game’s upcoming “Story Mode” being added in The War Within expansion may be expanded in the future. World of Warcraft is quite possibly the most famous MMORPG ever released, paving the way for future MMOs. After 20 years of being focused on the cooperative fight, Blizzard is adding a way for solo players to experience the last bosses of the game’s raid alone.
