Initially released in 1991, 'Sonic the Hedgehog' for the Game Gear is a side-scrolling platform game developed by Ancient and Sega. This version for Sega's portable console shares its name with the more famous Genesis/Mega Drive title but offers a unique level design and gameplay experience tailored to the handheld format. Players control Sonic, a blue hedgehog known for his impressive speed, as he races through levels to save his friends and collect rings while thwarting the evil Dr. Robotnik's plans. It's a classic installment in the Sonic series and an iconic example of the early '90s platforming genre.
