By winning first place in each world and grabbing all the chaos emeralds and coins throughout the map, you can unlock fun bonus characters like Metal Sonic, Dr. The nice thing is that you can use the 3D environment to your advantage! Incorporating 3D elements lets you take shortcuts for faster race times, and it will also help you find all the secret collectibles scattered around the world. But there’s no sugarcoating the fact that this game is hard to control - turning is frustrating and you’ll find yourself running into walls constantly. While Sonic R only has five courses, the exploration makes it more replayable. Not to mention, the game's theme song is super catchy! In Sonic R, instead of competing with race cars, Sonic and friends run to the finish line on foot, with each character having their own unique moves and abilities. Originally released on the Sega Saturn in 1997, Sonic R is an experimental racing game that set the tone for Sonic’s future in 3D. (Image Credit: Sonic Team, Traveller’s Tales)
