I usually don't like going to gamestop but how ever during the midnight release 2 of my other co-workers came to the same gamestop. Gamestop handled a event starting at 10:00pm across the board, they did trivial game at the gamestop I went to and did a raffle based on tickets earned during the games.
All night access to gamestop, and a few games to play.
They also gave away a few goodies a poster for sun & moon, landard, and wristband for pokemon Go.
They handed out pokemon cards, and riffled off pokemon sun, Moon, and plenty of pokemon cards. My wife won some, and so did one of my co-workers.
How ever they did not have any of the strategy guides which is kinda weird to not have one on launch night but understandable with it being launch but they should have one if they didn't receive a shipment. However that is very unlikely considering the work in experience I have with retail, more than likely corperate would not let them sell the strategy guides until the morning.
