The arcade intro
A first-time visitor is routed into a seven-screen attract sequence styled as a coin-op cabinet — title screen, where the collection came from, what the four ratings mean, the teams, the equipment, squad building, tip-off. It advances on arrow keys, swipe or the on-screen controls, and stamps a localStorage flag on mount so returning visitors land straight on the dashboard and are never routed back in.
A cold visitor has no idea what any of this is or why four numbers on a character should matter, and a conventional marketing hero would have to explain it in a paragraph nobody reads. Making the explanation the first level of the game teaches the rules in the voice of the product itself.
