Jordan Jackson writes "Hidden behind the line of eager players waiting their turn to play Zelda was a playable demo of Mario and Luigi 3: Bowser's Inside Story. Like the Zelda demo, it had several smaller segments, but I only opted for the Bowser one.
The demo started off by introducing Bowser's main attacks, punches and fire breathing, and both were needed to advance through the forest. After the third screen, monsters started showing up on the map, and touching them initiates combat. Anyone familiar with a Mario and Luigi game will feel right at home; they haven't changed the core mechanics one bit. With perfect timing, it's possible to avoid every attack and do a little extra damage to boot."
