"Sadly, most of the ~120,000 connections are not customers but via warez," he continued. "About 18,000 are legitimate."
The big lesson here (avoid any position where pirates can tax your resources) is pretty obvious in hindsight, so I won't belabor it. And I think the weak DRM on Demigod doesn't have anything to do with anything. No matter how strong your DRM is, Torrents of cracked versions of your game will be available in seconds.
I am just really drawn to this extra evidence of how overwhelming PC piracy is. 120000 users, 18000 legitimate! It dovetails nicely with what the World of Goo people found. No real conclusions here. Just my jaw hanging gently open.
