Super Mario World 2: Yoshi's Island is an absolute masterpiece that still holds up today. The hand-drawn art style is gorgeous, levels are creative and challenging, and the whole egg-throwing thing is way more fun than you'd think. Plus, Baby Mario's crying is kind of annoying at first, but it grows on you in a weird way! If you love classic platformers and don't mind the slower pace, this one's a must-play.
