I live by a GameStop, so I've had to hear the "crowds" of people cheer for Call of Booty, Halo, and everything Blizzard and Rockstar make. The Call of Booty crowd is the worst, which isn't surprising at all.
The only time I ever waited in line for a game was Super Smash Bros. Brawl. And boy oh boy, most of those people didn't know diddly squat about smash bros. Seriously, two people argued if King Dedede was going to be playable, despite being confirmed as playable about half a year beforehand.
However, there were some people who were really knowledgeable about the series.
Also, this is sadly very accurate. Although, again, it is missing people who think they know everything about the game, but in all actuality, don't know anything about it.
