Nintendo events are events held by Nintendo at game stores and toys r us when Pokemon movies come out on DVD these events give away Pokemon uncatchable in the Pokemon versions that the event Pokemon can go in Example if the event Pokemon is mew firered, leafgreen, ruby, sapphire, emerald can get it.
Nintendo events are real life events hosted by Nintendo. If you're hoping to get a ticket such as the Mystic Ticket, or Auorora Ticket, your out of luck seeing as Nintendo events only come once per serving. The only way to get these tickets now, is either linking with someone who has them, cheating, or buying them off e-Bay.
