I still think the name was changed because Yoshi's Story was kind of technically Yoshi's Island 2, but if they called it Yoshi's Island 3, they'd confuse most people and **** off the few that got that they were acknowledging Yoshi's Story (I actually liked YS, though). The only thing I didn't like about it was the baby-switching. Same thing as SM64DS; throwing in arbitrary obstacles and gimmicks just to force you to switch between characters. If each level was just one baby (and most of them were Mario), it would have been good. Also Luigi should have been playable.
Well, carryable, actually. You're really playing as the Yoshis, not the babies.
