In my high school's lobby, there's always these three poster things that get changed periodically, and they're always ads for something. Since I'm never in the lobby, I don't know how long it's been there, but I saw a Zelda: Wind Waker ad there today. It was an aerial view of like, this forest, and in the middle of all these trees was a castle with a huge tower. at one corner of the ad, it said "YOU", all through the forest in various places it said "THEM", then at the tower of the castle it said "HER." I thought that was so awesome.
Last year or the year before, there was a GBA ad with a Tony Hawk game, and it said "Study hall advanced." And back in 2000, there was a Paper Mario ad at the poster things near the gym.
It seems that Nintendo does a lot of school advertising. Too bad the only other person I know in my school who owns a GameCube is this girl who only has 1 game (Pikmin).
