Here are ten photographs of ten men who either helped build the video games industry as we know it - or were responsible for the deaths of countless innocent people.
Can you tell the video game pioneers from the murderers? Put your powers of deduction to the test, as we play... Video Game Pioneer - or Murderer?!
Or was he actually a serial killer, who dissolved his victims in a drum of hydrochloric acid, earning him the nickname "Acid Willy"?
Take a good, long look at his photo. Not so easy is it?
Its creator Steve Russell should rightly be heralded - if he did indeed create the game, and wasn't in actual fact a brutal killer, who drowned four high school cheerleaders during a week-long reign of terror in a small Midwestern town.
Again: look at the photo before making your choice.
Look into his eyes: are those the eyes of a video gaming pioneer... or the soulless black pits of a cold-blooded killer?
Unless Ted Dabney was actually a would-be presidential assassin, whose botched attempt on the life of President Eisenhower ended in tragedy when - cornered in an Atlanta launderette - he shot two policemen, before turning the gun on himself.
There he is in one of the only known photographs of him. That in itself should be a clue as to this why this individual has gone down in infamy...
Well, unless you're being spun another untruth with this statement.
Was Nolan Bushnell actually the man responsible for poisoning over thirty Chuck E. Cheese customers, in a twisted revenge attack on his former employer, who had fired him for punching a co-worker - by sneaking into the kitchens and lacing the food with strychnine?
It's time to choose!
1) Roy Trubshaw created MUD - the Multi User Dungeon, the predecessor to every MMO you've ever played.
2) Roy Trubshaw created a MVD - the Multi Victim Dungeon, a basement slaughterhouse, beneath his parents' house, into which he lured seven young men to their deaths.
Or did Crowther embark on another sort of "cave adventure", orchestrating three ritual killings as the high priest of a subterranean black magic sex cult?
See if you can work it out from his photograph...
Equally, Ed Logg could've been better known as "The Lumberjack" - a serial killer in the Boston area in the late-1970s, finally identified by the distinctive leather gauntlet he would wear while strangling his victims with an asteroid tied to a centipede.
Or did Howard Scott Warshaw merely represent the worst of humanity, as the leader of a paramilitary cult, who buried his 200,000 victims in a mass grave in New Mexico?
Look at the photo. You must decide immediately, before he kills again (or doesn't - if he isn't in actual fact a murderer).
