Well it seems that I just keep finding more Tiberium references, it seems that in this video there’s an obvious reference to Tiberium. I’ve looked up to try and see if there are any other references to Tiberium anywhere, and I can’t seem to find any, so it seems Command and Conquer and just general geekship is making itself more mainsteam in things these days. I wonder if “Average Joe” would know these references.
Edit: Thanks to Skillers of Techious, which in this thread (also people in a CnC forum thread) pointed out the other references that I should have noticed. So it seems that all these references are becoming more and more common.
