Mancala
Mancala is one of the oldest known games to still be widely played today. "Mancala" is a generic name for a family of two-player turn-based strategy board games played with small stones, beans, or seeds and rows of holes or pits in the earth, a board or other playing surface. The objective is usually to capture all or some set of the opponent's pieces. Versions of the game date back to the 7th century, and evidence suggests the game existed in ancient Egypt.
Real-time strategy
In the United Kingdom, the earliest real-time strategy games are "Stonkers" by John Gibson, published in 1983 by Imagine Software for the ZX Spectrum, and "Nether Earth" for ZX Spectrum in 1987. In North America, the oldest game retrospectively classified as real-time strategy by several sources is "The Ancient Art of War" (1984), designed by Evryware's Dave and Barry Murry, followed by "The Ancient Art of War at Sea" in 1987.
