I know the '90s were a time of strange FMV gaming dead-ends, especially on the 3DO, but Duelin' Firemen seems like such a strange beast that Idle Thumbs must know about it. Yes, even despite the fact that it was never released and exists only as the strangest game trailer ever made:
With cameos by Rudy Ray Moore, Tony Hawk, Mark Mothersbaugh, and Dr. Timothy Leary. All it needs is Jeff Goldblum.
