The NFL could return to Dublin again in the future, according to organisation's Vice President and Head Of Event Operations, Jon Barker.
The Pittsburgh Steelers and Minnesota Vikings are set to meet at Croke Park on Sunday for a first-ever regular season game on the island of Ireland.
The Irish government contributed around €10million to the cost of putting on the game, with roughly 30,000 of the 75,000 people going to the Jones' Road venue expected to have travelled from abroad.
The slightly lower capacity than normal, for an All-Ireland final for example, is related to the fact that seating has been put in place on Hill 16, which is usually a standing terrace.
Speaking to RTÉ Sport's Damien O'Meara, Barker suggested that a return to the home of the GAA is possible in the future.
"We're not going into a market, playing a game and leaving," he said.
"This is about building roots. It's about building fandom. The game is a catalyst. It's one three-hour day out of an entire year.
"This is about the other 364 days building the game of football and we sent those gift packets out to all the primary schools with flag football kits in them.
"It's about the sport and enjoying the sport. We love this game and the ability to bring it here and the ability to share it with the people of Ireland. It's really important to us and I'm glad we can do it.
"We don't want this to be an American football game being played here. When you see the game on Sunday, I think that we are authentically representing Irish culture in a real way and that's what this is about.

"This is your game. This is your city. We want to make sure that we're showing the rest of the world what Dublin has to offer."
Sao Paulo has already hosted a game this season, with fixtures in Madrid, Berlin, and three in London to come before Christmas.
In the past, Mexico City, Frankfurt and Munich have played host to games in the international series, while Melbourne is also in line to feature a match next year, so it's clear there's demand and competition for these NFL extravaganzas.
Pressed on whether this Sunday might be the first of many NFL regular season games taking place in Dublin in the future, Barker added: "We look forward to it. It's such a beautiful place."
