We have American football, baseball, and basketball. Canada has ice hockey, baseball and Canadian football. The West Indies and the Indian subcontinent have cricket (also field hockey in South Asia). The Irish have hurling and Celtic football. New Zealand has rugby. Australia has Australian football, rugby and cricket. South Africa also went in big for rugby (though recently soccer has come into its own there). East Africa, apparently, has running.
So all the countries where there's any genius at creating sports and games (except Britain) itself, have more or less rejected soccer or subordinated it to other sports. So sure, let's all learn about soccer, but don't be surprised if it's always a second-tier sport over here.
Of course, you could adapt the game to make scoring more likely -- a smaller field, a larger goal, no offsides rules. Cricket did that to stay competitive. But I wouldn't count on soccer making the changes or America casting aside other games to embrace soccer even if it did change.
Very interesting map. According to it, basketball predominates in the Baltic states, of all places.
