I am very curious why NHL has never been to France for one of these games (in the modern era). I know hockey is not the most popular sport, but it isn't dead like in Belgium or 99% of Spain.
Personally I would do,
2015-16
2-3 games in France (One game definitely in Paris, featuring Canadiens)
1 game in Norway (Featuring the New York Rangers)
1 game in Denmark (Featuring either the Canadiens or Canucks)
Maybe 1 game in Milan
Then in 2016-17
1 game in Tokyo (Trust me, if London can sellout a hockey game, so can Japan)
1 game in South Korea (Probably Seoul)
1 game in China (Shanghai since the China Dragons play there, but would prefer Beijing)
Maybe 1 game in Northern Japan where hockey is more popular
Future Locations
Australia
Hungary
Slovenia
Croatia
Maybe UAE
Maybe Iceland
Only problem with the Asia tour is a reasonable time for North America.
