Siege Perilous: Quest for the Grail was a game developed on an SGI Crimson Reality Engine eventually to be ported to the Hasbro Virtual Reality system. Unfortunately, Hasbro pulled the plug on their cool project, leaving the developers with nothing to show for their efforts. It's too bad because Siege Perilous (formerly known as Launcelot's Quest) would have been a real eye opener to the gaming industry. Siege Perilous was created for Virtual Reality Games (VRG), headed by Warren Robinett. The programmers were Erik Erikson (my brother) and myself. The artists were Steve Reid and Chris Kemple. Erik, Steve, and Chris currently work at Red Storm Entertainment.
