I've been waiting for TES:V since the day Oblivion came out, and I've decided to go to the midnight release for it at my local gamestop.
This is my first midnight release, but I have a problem. Curfew here is 11pm for those who are under 18. I happen to be 17, old enough to purchase Skyrim, but not old enough to meet to have no curfew.
If I am just outside gamestop with other people, or inside(I don't know how these work, are you in our outside the store?), can I get in trouble with the law?
I'm nervous.

I think you'll be ok. I think I went to midnight launches when I was 17.. I don't think they strictly enforce curfew. It's not like you're walking around by yourself in the middle of a parking lot.. There are other people there too. You'll be ok.
If there are a lot of people, the line will be outside.. But I've been to a few and they let you wait inside and they have had pizza and stuff. I'm guessing there won't be a huge line.. This game doesn't (at least I think) have a huge fan base like MW3. (plus it's cold, so you could wait in your car)
