I don't like knowing what something's going to be without experiencing it myself. That's why I was so careful not to trash Daikatana until I played the demo. That's why I commend what 3D Realms is doing with Duke Nukem Forever. The more gamers can be held in suspense, the better their initial experience will be. If I hear leaked information, I take it with a grain of salt.
Leaks are usually less than reputable to begin with.
People who bitch about leaked information are stupid, honestly. If you're willing to raise a clamor about something you think might be true, you've got too much time on your hands. As far as the mission pack goes, I don't like teamplay, but I'll certainly be giving it a try. Contact us for more information on GameSpy Industries.
