I love that the trailer is in English despite obviously utilizing a Japanese world. I can count on one hand the number of times I've run into a random person with a DS and the same games as I have.

I understand that in Japanese you've got a lot of people in a much smaller space, so it makes sense that stuff like this could come up and be awesome, but these guys really need to understand that for most Americans, random wireless-range playing isn't going to happen. Give us support for fucking online games against opponents.
