In many parts of the world, having a 3D graphics card is a luxury. Are you going to argue that the game should support software rendering?
No because that would probably make developing the game more expensive and also probably more expensive for the end user. Presumably, packaging DRM with a game doesn't make it
cheaper to develop (unless the DRM providers are paying the developer, but I don't think it works that way - I'm not sure).
So your argument here is kinda pointless isn't it?
In many parts of the world having a computer at all is a luxury! We should make Civilization 5 a board game instead.
An attempt at a joke?
The overwhelming majority of the target market have a persistent internet connection. Almost all of those who do not, still have intermittent internet access - more than enough to activate a game online.
The fact is that if you don't have internet access - none at all, even if you wanted it, there is no way you could connect to the net - you are in a minuscule minority of modern gamers.
Whether you like it or not, you ARE living in the past - be it for geographical reasons or what ever. And you are outside of the target demographic of most games which require online activation and it would be ludicrous to think that you are going to have any sway over the direction of a modern game.
I'm living in the past am I? Apparently, to live in the present, you require internet connection.
I'm not expecting to have any sway over the steam-only or steam-optional decision that will (or more likely has already has) be made. Nor should you expect to. At best if Civ5 is steam only, it will be a nuisance to me. I will probably still buy it, but it will not produce any loyalty in me to desire more Firaxis games.
There's going to be a Steam version and a non-Steam version - it's what 2k/Take-Two have been doing lately. The non-Steam version is still going to have some crappy DRM like Windows Live that requires an internet connection to activate, though. I would bet copious amounts of money on this.
Probably.
Yes, you can back up steam games to a disc or harddrive. I do it. Thus, your entire post IS moot.
I know it's not right to say anything "personal" but it seems rude to me to call my entire post moot. Argue against it if you will, but to state one fact and claim it makes my post irrelevant (which I assume is what you mean by moot) to me is like trolling because you make no attempt to say why.
This post is to clear up information about Steam, since 90% of you seem to be misinformed. This is a list of what steam is and isn't; nothing more, nothing less.
Steam & Offline Gaming
Steam does not require you be online to play your games. It works just fine in offline modes as well.
...
For someone who wants to install a game offline, can it be done if it is steam-based?
If not, as I said earlier, it does not make my post moot (I'll even include an exclamation mark to emphasise my point)... !
I have been many times in a scenario where I have had to re-install a game (typically through modding accidents or windows installs) and have not necessarily had a computer connected to the internet (e.g. taking a computer on holidays).
If a Steam-based game can be installed completely offline,
including updates/patches, then my problem would be moot. Is this possible?
Playing devil's advocate here:
Why not? You do this to everyone else every day. Don't you lock your door when you leave your home? Don't you trust the average person? Why treat average people like criminals?

I would have thought the answer to this was quite obvious. You are not trying to sell anything to "average people". Why do you think it is that in most supermarkets that have those alarms at the end of their registers, that when one of them goes off as a customer walks out, no one stops them? Hassling a paying customer over a bottle of shampoo or something that they paid for anyway is probably only going to piss them off and they'll never shop there again.
If I'm trying to sell a product to someone, I'm not going to treat them like a criminal. That would be one of the easiest ways to ensure a lost sale.
If I went to a bookstore and found a book I thought I'd enjoy, but learned that to open it required first activating it online, and thereafter you had to use a little security keycard in its vicinity to open it, I'm not likely to bother with a purchase because of the extra hassle. DRM lovers would have us believe the way of the future is to make sure this hassle is always there just so devs can feel better that their games are not being copied.
Anyway, I can't remember if I said this earlier in the thread, but my main point is this:
If the game were steam-based
only, more than likely it would significantly affect (negatively) the total number of sales. If Steam was optional, and there was an alternative NON-steam hard copy version available, there could only be more sales.
