In 1989, the Super Famicom was released in Japan, along with the eagerly anticipated Super Mario World. The following year, Nintendo released the console as the Super NES in North America, along with Super Mario World, while Sega released Sonic the Hedgehog for the Genesis.[52][53] Sonic showcased a new style of design made possible by a new generation of hardware: large stages that scrolled in all directions, curved hills, loops, and a physics system allowing players to rush through its levels with well-placed jumps and rolls. Sega characterized Sonic as a teenager with a rebellious personality to appeal to gamers who saw the previous generation of consoles as being for kids.[54] The character's speed showed off the hardware capabilities of the Genesis.
