Go (game)
Go is an abstract strategy board game for two players, in which the aim is to surround more territory than the opponent. The game was invented in China more than 2,500 years ago and is believed to be the oldest board game continuously played to the present day. 
A 2016 survey by the International Go Federation's 75 member nations found that there are over 46 million people worldwide who know how to play Go and over 20 million current players, the majority of whom live in East Asia.
History of role-playing games
Wargames have origins in ancient strategy games, particularly Chess. It originated as Chaturanga, created in the 6th-century Indian subcontinent as a simulation of ancient Indian warfare, particularly the Kurukshetra War (from the Indian epic "Mahabharata"), with pieces representing roles such as rajas, mantri (counselers), infantry, cavalry, chariots and war elephants. Chaturanga is considered the most ancient ancestor of "Dungeons & Dragons". According to RPG designer John Wick, Chess can be turned into a role-playing game if chess pieces such as the king, queen, rooks, knights or pawns are given names, and decisions are made based on their motivations. According to Wick, "Dungeons & Dragons" was a "sophisticated, intricate and complicated combat simulation board game that people were turning into a roleplaying game" just "like giving your rook a motive" in Chess.
