Haha wtf, a mic for animal crossing, no thanks.
If they could make, like, a 2-4 player split screen mode I'd LOVE that... I always hated waiting for my brother to get off the GC to play. It'd work fine; you'd all be in the same town, running into each other during various tasks, and it'd take away the feeling of "hey there's no-one else alive in this town".
