Retro Bowl's popularity outside of America is somewhat limited due to its strong American football focus, a sport that doesn't have the same widespread appeal globally. While American football has a dedicated fanbase in countries like Canada and parts of Europe, it is far less popular than other sports like soccer, basketball, or even rugby. Additionally, the game’s nostalgic, retro styling and mechanics may not resonate with all players, especially those unfamiliar with the nuances of NFL-style gameplay. As a result, Retro Bowl primarily attracts American football enthusiasts, which limits its broader international appeal.
