You can find in stores GCII: Gold which has GC: Dread Lords and Dark Avatar; and I believe that once 2.0 is released they will be releasing GCII: Endless Universe (DL+DA+TA) that will include the most up-to-date versions at the time of release. However, you need an Internet connection to register your serial in order to allow you to download future updates through Stardock's Impulse Utility. There is a work-around (it still requires internet access, but say like a library or a friend's computer) but in that case you would need to follow the steps and contact procedures for that.
My suggestion: If you have a bit of patience, 2.0 is "supposed" to be released next month, though there is the chance it could up to a month longer, i mean one never knows, but that can be an early Thanksgiving, Christmas, Hannukah, Kwanza etc etc present, to oneself
. i believe you can pre-order but don't quote me on that.
OR
I believe you can contact Support and you can download from another computer and transfer, but there are some limitations and they may have changed their mode of support for this form of action.
Its a great game and I hope that you get a chance to enjoy it soon
