I was standing in the Nintendo NY grand opening line, so I want to give a little context.
The line was around 8-10 hours long. Yeah, that long. Most of that was because of excessively poor planning by store management. They let in very, very few people at any given time, had a meet-and-greet that was poorly planned, and didn't force people out. Once people got inside, they were either stuck in the M&G line for a couple more hours, or weren't inclined to leave. That meant the line was artificially long. The next day, I was able to walk into the store with absolutely no wait or issue.
The crowd was younger and a mix of high-schoolers (a lot of them) and 20-somethings.
That last part interests me. For HP, the hard-core fandom really goes across every age group. For Nintendo, the most passionate fans are children, or high-school/20-something gamers. These are very wealthy demographics. It'll be interesting to see how Universal's land will change this.
