The long gap has turned qualification into something bigger than a routine football achievement. It appears to have tapped into a generation of supporters who have spent years following Scotland through near-misses, false starts and summer tournaments that never quite delivered.
That contrast matters. The team may not always have rewarded the noise around them, but the backing has rarely disappeared.
There is also a hard reality to this World Cup: not everyone who wants to go will be able to afford it.
That tension feels central to the story. The appetite is there, but modern tournament football increasingly asks supporters to pay elite-event prices.
The opener against Haiti looks crucial. It appears to be Scotland’s clearest chance to settle early and give the support a result to carry into tougher games. Reports suggest Morocco and Brazil follow, which would leave little room for a slow start.
That is the next storyline to watch now: whether the emotion of the occasion can be turned into points on the pitch, beginning with Haiti and a night Scotland supporters have waited almost three decades to see.
