Nebojsa Radakovic (6 de junio de 2004). «Sonic R Review». GameRevolution. «I can understand that Dr. Robotnik uses the hovercar because he’s a low down dirty cheater, but what about, uh, what’s her name again? Oh yeah, Amy. Anyway, the plot to this game is simple. Dr. Robotnik has discovered the location of the Chaos Emeralds, and plans to take them again. So, he tricks Sonic into joining a race, the winner getting the precious gems. Tails follows Sonic because, well, Tails is a sheep. Knuckles decides he should join the race to prove that he is the best. And Amy? She overheard Robotnik’s plans and decided to help. Make any sense? Nah, didn’t make any sense to me either. Why didn’t this Robotnik fella just get the gems without involving Sonic at all? The only person who overheard him was Amy, and she’s just Sonic’s girlfriend. At least they’re no longer on the island of the flickies . . .»
