I have never been at a gamestore at launch day of a specific game.. Is it crowded?
Hmmm, I live in a smaller town, but the store never got that crowded on the launch days I've been to.
Here are a few I remember:
Animal Crossing City Folk - Not crowded at all. I think I was one of the few that bought it that day.
Super Smash Bros Brawl - I went to the midnight release. Sure it was crowded, but the line moved very quickly.
Pokemon Black and White - Crowded for sure, but it's Pokemon. The line moved fairly quickly, but I didn't mind waiting at all.
I assume Skyward Sword will cause a slight crowd, but nothing that will take an hour to sit through.
