I just got home from the Pokemon Black 2 & Pokemon White 2 pre-launch today. All I have to say is this: Getting free stuff is great.
The Pokemon Party that Nintendo World had is great, for the most part. The ew things I like about going to those events, namely the Pokemon ones:
Free stuff
Seeing Pokemon fans of all ages, race, place of birth and so on
Chit chatting with fellow Pokemon Fand
Seeing how Nintendo world is handing the event, seeing people getting force to the back of the line when trying to skip it. That's a bonus.
Getting my paws on the game before any of you get it.
Down sides:
Long lines.
Long waiting in said lines.
