Real-time strategy (RTS)

Real-time strategy (RTS) refers to a time-based video game that centers around using resources to build units and defeat an opponent. Real-time strategy games are often compared to turn-based strategy games, where each player has time to carefully consider the next move without having to worry about the actions of his opponent. In real-time strategy games, players must attempt to build their resources, defend their bases and launch attacks while knowing that the opponent is scrambling to do the same things.

A real-time strategy game may also be referred to as a real-time simulation or a real-time war game.

Real-time strategy games introduce new pressures into strategy and war games because they require players to make quick decisions as far as how to use resources and time attacks. Some of the most popular RTS game series' include "Starcraft", "Warcraft", "Command and Conquer", "Warhammer" and "Age of Empires".

Although real-time strategy games move much more quickly than turn-based games, gameplay can still be slowed down by degenerate strategies like turtling.
