This is, indeed, true. Steam will be used with Civ V and you will have to run it when you play the game, but it won't prevent you from playing mods - we're not interested in limiting you guys. We are using the system to get you guys to connect together and find content easily, to have updates conveniently, to have a system that doesn't require a DVD... Steam is all of those things.
Thank you for taking the time and effort to write this. I feel I must respond to some of your comments however.
First off, the idea of "limiting you guys."
-- I fail to see how adding a requirement to have Steam software installed on my computer is not limiting purchasers of Civ V who do not wish intrusive third party software to be installed on their computer, ever.
Second, the idea of "get you guys to connect together."
-- I do so when and how I wish using various forums, including this one. I do not need assistance with this, thank you.
Third, the comment about "find content easily."
-- Ditto. I have never had a problem finding "content", be it patches or mods, on the sites that provide them.
Fourth, the issue of "to have updates conveniently."
Previous versions of Civilization simply required one to press a button in a game menu and the updates would be found and installed. If and when I wanted them...because there are times when, because I have a game going that I do not wish to abandon, I will wait to install the latest update. I don't want a third party jamming updates down my throat.
Fifth, your comment that you want "to have a system that doesn't require a DVD."
-- I have already purchased games using firms like D2D and others that do not require a DVD, thank you. And these firms are not installing intrusive third party software onto my computer.
Finally, you comment that "Steam is all of those things."
-- But Steam is also a third party that offers me no benefit as a solo player; at least no benefit that I do not already have via other, less intrusive means which actually give me more freedom and peace of mind.
I must say that I will, for various reasons that others have already expressed so I won't go into here, will boycott any game that uses Steam. I wish to buy Civilization V, period. I don't want any part of a force-fed social computing scheme that has me beholden to third party firms that I know nothing of and want no part of.
Having Steam come with Civilization is, to me, kind of like inviting the mother-in-law along for the honeymoon...and the marriage, 'til death do you part, etc. It's inclusion adds no value for thousands of gamers and actually irritates untold others. In some cases it has failed to work properly and has even cut users off from the product they purchased under conditions that are not negotiable or have a means of appeal.
I see this decision to go to Steam as purely one of dollar economics for the game's producer, nicely spun and sugared up by marketers to make it sound like gamers' best interests are the reason for it. Am I bitter? You bet I am. I am a long-time solo computer gamer, have been for almost 25 years, and despite my deep yearning to play Civilization V, VI, VII, etc etc, I also want nothing to do with a scheme that installs yet one more intrusive piece of irrelevant third party software on my computer. So for this gamer, the Civilization saga ends with Civ IV.
