It's been a while since I've been to a midnight launch, but I vividly remember the one I attended for the first Wii. No-one was dressed up, there wasn't free pizza. It was basically a group of really tired people in a line not talking to each other. #hypetrain
If the video and pics supplied by Nintendo are anything to go by, this one seemed like an amazing party of some kind. The type where you post pics on Facebook and everyone talks about how enriching your life must be. They all click 'like'.
To be honest though, I'm not sure this was completely representative of the midnight launch experience. These are pics of the special fancy ones Nintendo organised. Looks like people enjoyed themselves at least.
Also -- you won't believe this -- someone dressed up as Mario.
