Lazer Cycle was a tron clone that was written for the BBC Micro by System 3. For years it has been suggested that C64 version was in production.
It was confirmed however in 2015 by Jazzcat and Mark Cale that the game was never considered for the C64 at all. Therefore we can close the case on this one!

:-) So yet more to add, question wise, what ever happened to….(adds Knuckles and now Laser Cycle).
