- Fantastic 4 Cracking Group — Italy, founded 1983
An early F4CG intro from 1987, linked on intros.c64.org to CSDb release 23571 — a crack of Shoot 'em Up Construction Kit. Demozoo catalogues this as "F4CG Cracktro 39," confirming the release year. Scene commenter Twoflower attributed the intro to Lezziero, placing it within F4CG's first wave of activity. One commenter described it as having "an oldschool-feeling" while acknowledging it was "quite ugly" — an honest assessment of a production from when the group was only four years old. F4CG was founded in Italy in 1983 by Ricky, making them one of the earliest cracking groups on the platform. CSDb records over 1,600 releases for the group across their multi-decade lifespan. By 1987, they were already producing numbered intros in the high thirties, demonstrating prolific output even in their early years. The intro's connection to SEUCK — one of the more popular creativity tools of the era — ties it to a specific moment in C64 gaming history.
