Since I missed the pre-orders, I'm with around 25 others camping outside our local Walmart. Its not that cold (46-degrees F), luckily. I have a blanket and a laptop. It's so quiet… our Tetris DS battles have ended and most are sleeping.
By the end, had about 7 people playing at the same time over Wi-fi. Thank you Nintendo for only requiring a single game-pack for multiplayer!
