Owner nationality: the AL has American owners and the NL has international owners. International can be based broadly: living or
working outside the US (now or in the past), native to another country, having a family member from overseas, or just your family heritage.
The international (NL) requirement should be easy enough to qualify. Unless you are a pure bred Native American, everyone else is from somewhere else, if you look far enough back in the family tree.
Franchise names: Should reflect the history or culture of your nation or heritage, or to remind competing nations of their mistakes, especially the British, French, or Americans (lotsa fodder there). Politically insenstive or non-PC is fine, crude is not.
Other: Friendly banter & challenges are encouraged, drunken rants about hockey, footie (soccer), baseball, basketball, football, the opposite sex, & popular culture are compulsory. No talking about CRICKET! Never. Unless England wins (which is the same as never).
