IMHO the difference between this and Timecube is that Timecube is the work of a sincere (and very ill) man trying to preach his message to the world. The Nibiruan Council appears to me to be a scam to sell books, videos, and workshops to gullible people.
I’m not sure why, but Timecube cracks me up while this thing just bores me. But that’s just me, YMMV.
