Ed Fries wrote a Frogger clone for 6502, vanished into Microsoft for decades (launched the xbox), then wrote a celebrated version of Halo for the 2600. "What was the first video game or product you worked on in the industry? My first game was called Princess and Frog and was published in 1982 . the year I graduated high school . for the Atari 800 home computer. I had written a Frogger clone for fun in 6502 assembly language called Froggie. Guys at the California game company ROMOX saw the game but it only said .by Eddy Fries. on it. Somehow they found the right Eddy Fries in the country (that would be me) and I signed my first game publishing deal."
