Real time strategy

Real time strategy (or RTS, for short) is a game genre. RTS games are usually war games. The player has control over an army or a group of units. In a level, some missions must be accomplished to advance to the next level. RTS games usually feature very advanced AI, which allows for them to have multiple difficulty levels and game modes.

Some key components of an RTS game include:
 * Gathering resources
 * Spawning units
 * Creating buildings

Nowadays almost all RTS games created are 3D. Before that, RTS games were viewed from an isometric view.

Examples of RTS games include Age of Empires, Stronghold, and Warcraft.
