Sonic CD is a clear example of classic Sonic gaming. I mean, it was so good, it was even re-released in 2011! It also marks the first appearances of well known characters like Metal Sonic. It features classic game-play and it is easy to play if you are a beginner. If you're a Sonic fan, old or new, it is essential to have this title. Even the graphics themselves, although they are old compared to today's, are beautiful and a technological achievement for 1993. The game even looks polished today and provides a good retro service. The music is very catchy. I recommend the Japanese/European track but the American one is good too. The only possibly bad thing about this game is that sometimes, especially in the special stages, it is quite hard. But other than that, Sonic CD is a great game and is an essential title for any Sonic fan.
