Stardock said "Fu@k you, we don't care about you" to anyone who doesn't have their gaming computer connected to the internet.
I agree with smartwings, I don't want to be forced to install another program just to make the game updateable. Granted, I've never had any problems updating either GalCiv or GalCiv II/DA...until now. I'm in the Army and deployed in Iraq and the only internet access I get is at an internet cafe where I don't even have access to the desktop, let alone any chance what-so-ever to install SDC to try the Download and Archive work around. These are the only games I own, and I own a lot, that I can't just download the patch from any computer, put it on a flash drive, and put it on my computer to use. That is 100% bullsh**. I paid good money for these excellent games, but right now I'm stuck at version 1.4. No re-done graphics engine for me. Even other companies that don't patch very well (Bethsoft's Oblivion, anyone?) at least let me download the patches from anywhere when they do decide to patch their games.
Actually, this is simply taking advantage of technology and going along with the flow. Many other games have an auto-update feature and using Stardock Central makes this process much more simple. In addition, Stardock's copyright protection method is simply that you must have a unique registration code in order to get patches. This is certainly reasonable enough, given that there is no other attempt to prevent pirating and Stardock Central, again, is an easy way to accomplish this. Rather than reinvent the wheel, it just makes sense that Stardock simple use existing software.
Besides many games involve installing additional software in order to unlock other features. Gamespy is a common one, but there are many, MANY others.
I personally think that the reaction to this and other things is not due to Stardock doing anything wrong--it's do to them doing things differently. It's one of the quirks of humanity that we often see different as wrong and buck against unexpected deviations from the norm. While Stardock's policies are not that much different from everone else's and even follow certain conventions, they are a still different, and people, for no good reason, don't like that.
