A 2D platformer and first entry on the SNES in the Super Mario franchise, Super Mario World follows Mario as he attempts to defeat Bowser's underlings and rescue Princess Peach from his clutches. The game features a save system, a less linear world map, an expanded movement arsenal and numerous new items for Mario, alongside new approaches to level design and art direction.

Mario is having a vacation in Dinosaur Land when he learns that Princess Peach Toadstool has been kidnapped by the evil King Koopa Bowser. When Mario starts searching for her he finds a giant egg with a dinosaur named Yoshi hatching out of it. Yoshi tells Mario that his fellow dinosaurs have been imprisoned in eggs by Bowser's underlings. The intrepid plumber has to travel to their castles, rescue the dinosaurs, and eventually face King Koopa himself, forcing him to release the princess.
