The game was released in conjunction with its 10th anniversary. That being said, the years haven't affected it at all, as it is still as fun to play as it was in its day. Also, this version comes with improved graphics, different special effects, and controls adapted to mobile devices.
Other new features in this iOS version include the ability to save your game online using iCloud, and the ability to create your own radio station with your songs from iTunes.
Otherwise the game is pretty much faithful to the original, offering a campaign that lasts several dozen hours, and puts you in the shoes of Tommy Vercetti, one of the most charismatic characters of the franchise.
Grand Theft Auto: Vice City was an outstanding game ten years ago, when it was released on PC, and it is still an outstanding game today on iOS devices.
