I'm not so sure. Go back to the 70's and 80's. The creator of Pacman was 25. David Crane was still in his 20's when he started Activision. Trip Hawkins was 29 when he started Activision. Will Wright started at 24. Mark Turmell (NBA Jam, Smash TV) was hired at Midway when he was 26 and was selling games as a teenager. Miyamoto joined Nintendo at 25. A huge amount of these guys were having games published when they were teens.
