Hahaha.There are lots of europeans people who already have their cartridge (even the local Amazon already shipped the game) on twitter and no one complained about a ban. Nintendo is not enough crazy to ban all the europeans who have their retail versions, as it's not a leak anymore so I would say it's safe to go online for the EUR version now.
The USA release date was different, as reviews weren't even published at that time and it was definitively a leak.
Hahaha.
Don't know what else to tell you people who wanna play with fire time and time again.
