Sonic Jam

Sonic Jam is a video game compilation developed by Sonic Team and published by Sega for the Sega Saturn and was the first Sonic the Hedgehog game to feature full 3D gameplay. It was released in Japan in June 1997, and in North America and Europe two months later. It contains the four main Sonic the Hedgehog games released on the Sega Genesis: Sonic the Hedgehog (1991), Sonic the Hedgehog 2 (1992), Sonic the Hedgehog 3 (1994), and Sonic & Knuckles (1994). It also features a 3D environment, "Sonic World", which doubles as an interactive museum of Sonic the Hedgehog content.
