Gabe Newell, who Forbes said is a name you should know, is best known as one of the founders of Valve. Valve, of course, is famous for games like sci-fi shooter Half-Life and multiplayer shooter Team Fortress. Valve makes great games!
Ever wonder what Newell's favourite games are? Well, his number one favourite title of all time is is Super Mario 64. Released in 1996 and designed by Shigeru Miyamoto, the game was a landmark title.
"I still have vivid memories of all the different levels," Newell tells website CVG. "The control is still pretty much unrivalled. It convinced me that games were art."
And Newell's second most favourite game? Why, Doom. Mario 64 might have convinced him that games were art, but Doom convinced him that games were the future of entertainment.
