File this under 'interesting'...
I caught this announcement on toy site Tomopop the other day. It seems that K'NEX is launching a Mario Kart line of building sets that very closely resemble LEGO bricks. Although K'NEX has always had minifigure-esque figures appear with their sets, it's the brick design that really surprises me.
On the figure side there are three so far - Mario, Luigi, and Yoshi. They come with their own 'power-up' items too. No news yet if other Mario Kart characters are slated.
