The Official Civ5 Steamworks FAQ has been posted over on the 2K Forums: http://forums.2kgames.com/forums/showthread.php?p=944015#post944015 And it's up before the end of July, just like I originally estimated! I have reproduced it in full here, as a courtesy to you: Spoiler : Q. Can I play Civilization V while not connected to the Internet? A. Yes. After you have activated your installation by launching the game once while connected to the Internet, you may restart Steam in offline mode. This will allow you to have access to Civilization V even while not connected to the Internet. Details on how to use offline mode are available on this Steam Support page: https://support.steampowered.com/kb_article.php?ref=3160-AGCB-2555 Q. Will I need to run Steam every time I want to play Civilization V? A. Steam will need to run when you play Civilization V, but an Internet connection is not required after the initial installation. Q. How big will the Civilization V download be? A. Its impossible for us to know for sure until the game is 100% finalized, but it will be in the same ballpark as many other Steam games. We will include this detail in our minimum specs when they are announced. Q. Will it be possible to preload Civilization V on Steam before the release date, so we can start playing it the moment it unlocks? A. Unfortunately it is too early for us to tell if this will be possible, but its definitely something we would like to do. Ill let you guys know as soon as we know for sure. Q. Will Civilization V use the Valve Anti-Cheat (VAC) system? A. No, we are not using VAC. This means that nothing you do in Civilization V would cause you to become VAC-banned, nor will a VAC-ban cause you to be unable to play Civilization V multiplayer. Q. When using offline mode, will I need to periodically reconnect to the Internet? A. No. Once you switch to offline mode you can stay in that mode forever. The one exception is that if you significantly change your computers hardware, you will need to switch to online mode and launch the game one time to reactivate the game. There is, unfortunately, no way for software to tell the difference between a change in hardware and a move to a completely new computer, which is why this happens. Q. If I use a personal firewall to block all network traffic to and from the Steam client, will Civilization V still function? A. If you have already configured Steam to run in offline mode, then yes. It would cause Steam to function as if you had no Internet connection at all, which works fine once you are in offline mode. Q. Will it be possible to get any required updates and patches on another computer to transfer via thumbdrive, or will they be only accessible via the computer the game is installed on? A. Patches will only be available to download via Steam. However, Steam does provide a method for backing up a game installation to restore on the same or different computer. You could use this feature to download a new version of Civilization V on a friends faster Internet connection and then transfer it to your computer via a thumb drive. After restoring the backup, you will need to connect to the Internet once to validate the new version. Details of how to use this feature are on the Steam Support page: https://support.steampowered.com/kb_article.php?ref=8794-YPHV-2033 Q. Will it be possible to play multiplayer via LAN when running Steam in offline mode? A. Yes, LAN play will function when in offline mode. Q. Will things like the steam community be fully integrated into the game's interface or will you be relying on the overlay to provide functionality like chat and friends lists? A. The in-game browser, friend list, friend invites, and some other features are embedded within the Steam overlay. However, the mod library and in-game chat during multiplayer matches are integrated directly in to the game. Q. What personally identifiable information does Valve collect with Steam? A. The only information players are required to provide is a valid email address and a password, and to verify they are older than 13 years of age. All other information at registration time is optional. Valve does track the time spent playing a game, per account, but does not collect information about what other processes are running concurrently on the computer. A players profile can be set to hidden, which prevents other people from seeing that players playtime statistics. These statistics are also recorded while in offline mode, and are transmitted the next time you connect in online mode. Crash logs do sometimes collect extra information such as what processes were running at the time of the crash, and these logs contain your Steam ID for tech support to use. Q. If I have a game of Civilization V running on my desktop at home (in online mode) and I log onto Steam on my laptop elsewhere, what happens? A. Your Steam account at home would become disconnected. Your home machine will not be able to access any online or community features until you reconnect to Steam. Q. If I install a mod from a third party website, will Steam need to validate the mod in any way? A. No. Mods will not be validated by Steam, and you will not need to switch steam to online mode in order to play a new mod. Q. When Steam auto-patches Civilization V, will mods cease to function until they are updated for the new patch? A. We do not review mods so we cant speak to the effect patches may have on every mods functionality. At the same time, ensuring that our platform remains stable and backward-compatible is a priority. As always, as I get more info, Ill update you. Q. How will Steam know that I bought a boxed copy of the game? A. The box will contain a product code that you use to register your purchase to your Steam account. The box will also contain a disc that contains the data files for the entire game. When you install from this disc, it will install Steam if necessary and then place all of the game files on to your hard drive, negating the need to download the game from the Internet. Q. Should I be concerned about where I buy the game from, when it comes to compatibility with future expansions or content? A. One of the advantages of using Steamworks is that no matter where you buy the game from, you can be sure that itll be compatible with any future content released. Q. Is there a limit to the number of times/computers you can install Civilization V? A. There is no limit to the number of times and different computers on which you can install Civilization V. Q. Is it possible to stop Steam from automatically patching Civilization V? A. The only way to ensure your game is not updated is to play in offline mode. If you are in online mode your game will be automatically updated. Q. Will it be possible to make a copy of the installation directory for the purposes of having multiple versions of Civilization V available to play? A. No, this will not be possible. Q. What is the possibility of a version of Civilization V being released that does not contain Steamworks integration? A. Much of Civilization Vs framework is built around Steamworks. There are no current plans to ever release a version without that integration. Q. What happens if my Steam account is hacked or stolen? Would this enable someone to steal the game from me completely electronically? How would I prove it was stolen? A. Valve has a support page detailing how to recover a stolen/hijacked Steam account. You will need to provide some sort of proof of ownership of the account. The details can be found at this support page: https://support.steampowered.com/kb_article.php?ref=2347-QDFN-4366 note that if Civilization V is the only game you have registered to your Steam account and you bought a boxed copy, you should be sure to save the original product key to use as proof of ownership. Q. Considering the fact that Steam is now available for Mac and many games are being offered as SteamPlay, will Civilization V be coming to the Mac? A. All Civilization titles have had a Mac version in the past, but we unfortunately have nothing to currently announce for Civ V. Stay tuned in the future! Q. How will I unlock the Cradle of Civilization Map Pack? A. The map pack will be automatically downloaded and installed through Steams DLC interface. Q. How do I view all registered extras (like map packs) associated with my Steam account? A. Here is a Steam Support page which details how to view all extras associated with a game: https://support.steampowered.com/kb_article.php?ref=2668-CFOM-1881 Q. Do customers need to download or install any other 3rd party program besides Steam to authenticate or install or play Civilization V? A. The game will detect and install the required version of DirectX when you launch it for the first time.
