I suggest that you can organize an international league.
1 、 Weekly or every two weeks have a game .
2 、 First season ，We can let the same level in each country consisting of an international league tournament ，After many rounds finalists,You can qualify for more advanced Cup.
3 、 Can be determined by the rankings with international World Cup , rather than friendly game .
and so on . I think it can increase people's interest in the BB.
