how many worlds are in the original super mario bros

He actually did almost make it into the 2008 Wii release, Super Smash Bros.

Geno has a bit of a rocky relationship when it comes to the Super Smash Bros series. Geno's skills were imperative in helping Mario and his allies repair the Star Road. Being a deputy of the Star Road, Geno is confident and heroic, yet friendly and well-mannered, even worrying himself about being able to return the young boy's doll to him. But since he's a wooden puppet and all, his physical and magical defenses are lacking ( something that our resident Schomer thinks the remake should address). He's very powerful, boasting strong physical and energy-based attacks. Geno is actually a star with the unpronounceable name '♥♪!?' that possessed the physical form of a young boy's wooden puppet doll, assuming that it was stronger than the dolls of Mario, Toadstool (the name Princess Peach used to go by), and Bowser. As he explains in one of his iconic lines, he works 'for a higher authority' as a star warrior, for the duty of repairing the Star Road and restoring balance and hope to Mario's world. Geno is one of the members of Mario's party. That's given Smash Bros fans hope that, at long last, one of their most requested characters may finally make an appearance in Nintendo's brawler. It's also praised for its amazing soundtrack, world-building of the Mario universe, and interesting characters, one of whom is the inimitable Geno, who'll be making the return. The original 1996 game has been adored throughout the ages as a great introduction to JRPGs. The recent Nintendo Direct was packed with great announcements, chief among them for me being the remake for Super Mario RPG: Legend of the Seven Stars.
