10. Rome
Rome, and most of the cities on this list, would offer GTA gamers a very different experience to the previous games. Roads in Europe are generally narrowed than US roads, there is less room for error but much more potential for gamers to cause pandemonium. Rome, and Italy, are famous for their sports cars and their classical architectures, and in the open roads surrounding Rome, you could push these cars to their limit. Venture into Rome however and these cars would become useless, as the roads in Rome are notoriously busy and the motorino (scooter) is king. Winding in and out of traffic on your scooter would be quickest way to travel and the easiest way to evade the police. When you factor in the narrow side streets and roadside cafes you have a vibrant, almost claustrophobic city, with open, fast, roads just outside the city limits. Rome is a perfect, albeit unlikely pick choice for GTA.
