A broadband connection to the Internet is highly recommended.
If you are experiencing a problem with out of sync (OOS) errors in Internet games from players trying to hot join into AI controlled Civs or from players retiring, have the host save the game and re-launch from the main menu.
If a player inadvertently drops from an Internet game, it is better to have everyone wait at the Democracy screen than to have the player hot join while the game continues.
Though multiplayer games can have up to 18 players we only support and recommend a maximum of 12 players.
