Yep and if the IP-warriors had their way there would be no Halo, no Everquest/Wow, etc. Its just incredible how these people back the most corrupt corporation's laziest IP theft claims and jump to defend them and mock everyone else as a "rip off."
Heck, even your example of Warfcraft wouldn't have happened because by the pro-IP crowd's standards, it would have been a "rip-off" of Dune II.
I remember when the tech community fought overly broad IP claims and patents, now its just pro-IP shills left and right. Its incredible how far we've fallen.
