Vice City was the perfect sequel, and seen by many as GTA's finest ever setting thanks to its campy 80s retro flavour, colourful cast and awesome neon-soaked Miami replica of a city. Where GTA III teased us with the possibility of flying around the city and experiencing it from the air - something you could pull off with a handy glitch using the Dodo - Vice City actually went there, offering players an assortment of planes and choppers to fly around Miami in. Even without flying craft, Vice City felt like one of the richest video game environments in existence, but suddenly you could land pretty much on any roof in the city you wanted. What do you do on these roofs? Throw grenades onto the street below, play a game of 'sniper serial killer', or just look down over the city like you own the place? It didn't matter, the point was that you had that option, which added a whole new dimension to the city at a point in the game when you'd thought you'd seen it all.
