Two epic games in the Mario timeline- Super Mario Brothers 3 and Super Mario World. One epic question- which one is better? For many, this is an incredibly tough question to answer- so feel free to debate and state your reasons for the better title.
For me, the better of these two is probably Super Mario Bros.3. It had brought so many new elements to the table-zany powerups, the map screen, the koopa kids and gambling houses. Super Mario World hardly did anything more than just update the graphics and throw in Yoshi and two extra challenge worlds. The designs in Super Mario Bros.3 were also noticeably better. Aside from the traditional Grass,Desert and Snow worlds we had gotten more interesting levels. For example, one world featured huge monsters and another a tower in which you needed to climb in order to reach the sky levels. There's also the airships and battle scenes to consider.
