The British kids a bit thick if he's trying to play round ball with an oval ball. But, we Brits have more than one game...

Rugby now, that'd almost work. American football evolved out of a number of European games, including rugby. So a rugby-playing British kid can play with an American kid who plays football, with both able to learn something from the other. Rugby players often play AF because it adds variety to their training. And both could play Aussie rules or Gaelic football too, maybe not as well as their own sport but they could still have fun togther.

Maybe that is what BG3 will become. Not quite either, but appealing to more because of it.
