I had to work at a midnight release for Halo 3 a few years ago. That was pretty weird, especially since I never really was much of a Halo fan at all and just did not want to talk all things Master Chief with the people who were there. Most of which were wearing helmets. It was odd. I did not know midnight releases were a costume thing. I suppose I should have expected something since I have been to many a midnight showing of movies and those also tend to be costume events for a lot of people as well.
Anyway that was a long night, way too busy for a game store at midnight. Including a few people who really did not want to leave at 1am. I expected most people to run immediately home after getting their copy to go play it. Not stick around for an hour.
I've never gone to one before, but I wanted to. Sadly, Skyrim released on a school night, and my Mom wouldn't let me go with my Church group leader, who is also a huge Skyrim Fan. I would want to go to a Midnight release though.
No, I have not, and I'm not sure I really want to either. I don't really crave to get any particular game. And I know that no game will truly ever be sold out until a few good years after release, so I can wait some time before getting any game I want.
The only midnight release event I've been to was the one for WoW: Cataclysm. And it was effing FREEZING. If MoP gets release during the coldest day of the year like Cata was, I will NOT be happy.... but I'd still go because downloading new expansions takes forever I found, so I'd go to the release event, start the download and let it go until morning so I can sleep, then play after a couple of days, because Cata release was nuts, and I couldn't enjoy the experience.
