As most of you know, Stardock games ship with zero copy protection.
That means someone could take Demigod and post it up somewhere. But so far, no one has even though Gamestop violated their agreement and released the game early. So the potential for "0 day warez" with Demigod is more so than most any other game because there's nothing to "crack".
We (Stardock) have always taken the position that people are fundamentally honest. I tend to think that things get warez'd because the copy protection provides a sort of challenge to overcome. Since Demigod has no such copy protection on the DVD, there's no challenge and hence no point.
Incidentally, we are working on a demo version as well that should be out as soon as we recover from the initial launch. 
Both Gas Powered Games and Stardock have poured their life and souls into this game. We're very proud with how it turned out and we thank those of you who have pre-ordered for sticking with us despite it being available. We'll definitely find some way to thank those users in the future. We look forward to playing with you guys online and hanging out together in the growing Demigod community.
Happy Easter everyone!
