Game: Sonic CD

Retro games on mobile have been something of a hit or miss proposition. Sometimes bringing a classic to the iPhone can be a flawless celebration of everything that made the game great 20 years earlier. Other times it can be a total disaster. But for the most part, Sonic's experiences on smartphones have fallen somewhere in between. Competent, but never feeling quite right in terms of gameplay. All of that changes with Sonic CD - a game that's easily one of the best old school mobile ports we've seen to date.
