What are succession games?
Succession games (SGs) are games of single-player Civ4 played by a team. For example, a host will start a game with all the settings he wants in the Succession Game forum, and wait for interested people to sign up to play. Once a team has assembled (usually around 5 players), the game will begin and players will take their set of turns one after another. In most SGs, each player plays 10 or 15 turns per round. After posting a log of their actions (worker actions, unit movement, any warfare, diplomacy, etc.), the next player takes their turn, and this cycle continues until the game ends.
