From http://wiiudaily.com...-world-trailer/
Yoshi has been a dedicated companion of the Mario Bros. since Super Mario World, but when he’s not busy sacrificing himself so you can get that extra boost in your jump, he’s starred in quite a few games of his own over the years. The trailer doesn’t showcase my personal favorite Yoshi game, Yoshi’s Cookie, but it does take you through the history of the Yoshi’s Island games.
Yoshi’s Woolly World is a continuation of the same gameplay that developed in the Yoshi’s Island series, only there’s no baby Mario to worry about losing.
