According to the latest issue of Nintendo Power, WiiConnect24 will allow other people's Miis to wander into your game, equipped with the student profiles of their creators. You will also be able to test your brain against theirs in any of the multiplayer modes. We're going to be pretty depressed if our friends' Miis turn out to be much smarter than us. At least we have our wit! There's always that, right?
Big Brain Academy won't be coming out in the US until June 11, so there's still some time to hit the books and get your brain in shape. Jeux-France has several dozen screenshots of the game in action along with some Mii artwork. Check past the post break for a few of those images.
