World of Warcraft is superficially similar to numerous other games that came before it, and it clearly draws inspiration from some of them. The fundamentals are all here, such as fighting dangerous creatures (optionally including other players), exploring the countryside either alone or in the company of other players, undertaking various quests, gaining experience levels and new abilities, and acquiring powerful items. However, directly comparing World of Warcraft with any of its predecessors would be almost like pitting a professional sports club against a school team. With all due respect to the other online role-playing games out there, World of Warcraft is in a league of its own.
