The 2003 Warcraft III Mod known as Defense of the Ancient (or simply DotA) fanned the popularity of a new multiplayer sub-genre called MOBA which eventually gave rise to other similar games. Multiplayer Games cover a wide array of gaming genres, some of the most popular genres are shooting and racing. Some of the earliest large-scale networked multiplayer games include the StarTrek-based title called STAR, a naval war simulation called OCEAN, and a Dungeons and Dragons-style RPG called CAVE - all of which were developed and released around the 70s. An early example of local multiplayer is the space-themed combat shooter Spacewar! that was released back in 1962. Before that time, multiplayer games are mostly played in a local unit or gaming console.
Real-time multi-user titles weren't developed until around the 1970s.
