This ad is rather unusual, in that it implies tormenting a little brother. It states "Your little brother will regret that he exchanged your old Sonic games for a long time" and shows someone tied up, in a dark room. Of course, this is meant to draw attention to the lock on feature that S&K had...but wouldn't showing Knuckles actually playing around in some other level (ie distinctly in Sonic 3 playable areas) be more effective?
