A turn-based strategy (TBS) game is a strategy game (usually some type of wargame, especially a strategic-level wargame) where players take turns when playing. This is distinguished from real-time strategy (RTS), in which all players play simultaneously.
After a period of converting board and historic TBS games to computer games, companies began basing computer turn-based strategy games on completely original properties or concepts. The presence of a computer to calculate and arbitrate allows game complexity which is not feasible in a traditional board game.
Some well known turn-based strategy games are Final Fantasy series, Sid Meier’s Civilization series, Heroes of Might and Magic series, Panzer General series, Warlords series, and Age of Wonders series.
