The retail boxed version of the game requires nothing at all. No serial number, no CD in the drive, no CD check, nothing.
But for users who have downloaded the free updates of the game from us (at which point you obviously have some Internet access) those updates require the serial #.
You do NOT have to have an Internet connection to play the game. IF you do have an internet connection, then the game will talk to the server ONE TIME and create a sig.bin file. If you're using Stardock Central, this is all automated and users don't even notice this.
If you're not on the net, a dialog pops up with instructions on getting a key to type in which involves emailing us and getting it back. Usually takes an hour if it's during a weekday, a day if it's at night.
But you don't have to get 1.1. It's not a required update. You could stay with 1.0X indefinitely or the retail boxed version.
Moreover, our system is NOT like Windows activation or whatever. You can install the game to your laptop, your desktop, your work machine, etc. It only brings up a flag if it's being installed say 1000 times a week from different parts of the world.
Our system has been in place for years and we've always been very vocal about it -- we do not like CD copy protection. We protect our games by giving users a reason to buy it in the first place -- by providing free, real updates. One look at the 1.1 update log and I think people will agree that it's not an ordinary "patch". All we ask in return is to type in the serial # that came with the game.
And in return for typing in that serial #, you can redownload THE ENTIRE GAME even years from now when you've lost that CD. If we didn't have this system, we wouldn't be able to do that.
I am willing to make the case that more users benefit from being able to redownload the game in its entirety indefinitely afterwards than the number of people who are inconvenienced from having to type in a serial #.
As for Stardock orphaning it's stuff, we've been in business 13 years. We're not going anywhere.
